Connection diagram of the vortex heat generator to the heating system. Potapov heating plant. T. Henry Morrey's generator

For heating premises or heating liquids, classical devices are often used - heating elements, combustion chambers, filaments, etc. But along with them, devices with a fundamentally different type of effect on the coolant are used. Such devices include a cavitation heat generator, the work of which consists in the formation of gas bubbles, due to which heat is released.

Device and principle of operation

The principle of operation of the cavitation heat generator is the heating effect due to the conversion of mechanical energy into heat. Now let's take a closer look at the cavitation phenomenon itself. When excessive pressure is created in the liquid, vortices arise, due to the fact that the pressure of the liquid is greater than that of the gas contained in it, the gas molecules are released into separate inclusions - the collapse of bubbles. Due to the pressure difference, the water tends to compress the gas bubble, which accumulates a large amount of energy on its surface, and the temperature inside reaches about 1000 - 1200 ° C.

When the cavitation cavities pass into the zone of normal pressure, the bubbles are destroyed, and the energy from their destruction is released into the surrounding space. Due to this, thermal energy is released, and the liquid is heated from the vortex flow. The operation of heat generators is based on this principle, then consider the principle of operation of the simplest version of a cavitation heater.

The simplest model

Rice. 1: Functional principle of the cavitation heat generator

Look at figure 1, here the device of the simplest cavitation heat generator is presented, which consists in pumping water by a pump to the place of the pipeline narrowing. When the water flow reaches the nozzle, the pressure of the liquid increases significantly and the formation of cavitation bubbles begins. When leaving the nozzle, the bubbles release heat power, and the pressure after passing through the nozzle is significantly reduced. In practice, multiple nozzles or tubes can be installed to increase efficiency.

Potapov's ideal heat generator

The Potapov heat generator, which has a rotating disk (1) installed opposite the stationary one (6), is considered an ideal installation option. Cold water is supplied from the pipe located at the bottom (4) of the cavitation chamber (3), and the outlet of the already heated one from the top point (5) of the same chamber. An example of such a device is shown in Figure 2 below:


Rice. 2: Potapov's cavitation heat generator

But the device did not receive wide distribution due to the lack of a practical justification for its operation.

Views

The main task of the cavitation heat generator is the formation of gas inclusions, and the quality of heating will depend on their quantity and intensity. V modern industry There are several types of such heat generators, which differ in the principle of generating bubbles in a liquid. The most common are three types:

  • Rotary heat generators- the working element rotates due to the electric drive and generates fluid swirls;
  • Tubular- change the pressure due to the system of pipes through which the water moves;
  • Ultrasonic- the inhomogeneity of the liquid in such heat generators is created due to sound vibrations of low frequency.

In addition to the above types, there is laser cavitation, but this method has not yet found industrial implementation. Now let's consider each of the types in more detail.

Rotary heat generator

It consists of an electric motor, the shaft of which is connected to a rotary mechanism designed to create turbulence in the liquid. A feature of the rotor design is a sealed stator, in which heating takes place. The stator itself has a cylindrical cavity inside - a vortex chamber, in which the rotor rotates. The rotor of a cavitation heat generator is a cylinder with a set of grooves on the surface; when the cylinder rotates inside the stator, these grooves create inhomogeneity in the water and cause cavitation processes.


Rice. 3: design of the rotary type generator

The number of recesses and their geometrical parameters are determined depending on the model. For optimal heating parameters, the distance between the rotor and the stator is about 1.5 mm. This design is not the only one of its kind; for a long history of modernizations and improvements, the working element of the rotary type has undergone a lot of transformations.

One of the first effective models of cavitation transducers was the Griggs generator, which used a disc rotor with blind holes on the surface. One of the modern analogues of disk cavitation heat generators is shown in Figure 4 below:


Rice. 4: disc heat generator

Despite the simplicity of the design, rotary-type units are quite difficult to use, since they require accurate calibration, reliable seals and compliance with geometric parameters during operation, which makes them difficult to operate. Such cavitation heat generators are characterized by a rather low service life - 2 - 4 years due to cavitation erosion of the body and parts. In addition, they create a fairly large noise load during the operation of the rotating element. The advantages of this model include high productivity - 25% higher than that of classic heaters.

Tubular

The static heat generator has no rotating elements. The heating process in them occurs due to the movement of water through pipes tapering along the length or due to the installation of Laval nozzles. The supply of water to the working body is carried out by a hydrodynamic pump, which creates a mechanical force of the liquid in a narrowing space, and when it passes into a wider cavity, cavitation vortices arise.

Unlike the previous model, the tubular heating equipment does not make a lot of noise and does not wear out as quickly. During installation and operation, you do not need to worry about accurate balancing, and if the heating elements are destroyed, their replacement and repair will be much cheaper than with rotary models. The disadvantages of tubular heat generators include significantly lower performance and bulky dimensions.

Ultrasonic

This type of device has a resonator chamber tuned to a specific frequency of sound vibrations. A quartz plate is installed at its input, which vibrates when electrical signals are applied. The vibration of the plate creates a ripple effect inside the liquid, which reaches the walls of the resonator chamber and is reflected. During the return motion, the waves meet with forward vibrations and create hydrodynamic cavitation.


Rice. 5: working principle of the ultrasonic heat generator

Further, the bubbles are carried away by the water flow along the narrow inlet pipes of the thermal installation. When passing into a wide area, the bubbles collapse, releasing thermal energy. Ultrasonic cavitation generators also have good performance as they have no rotating elements.

Application

In industry and in everyday life, cavitation heat generators have found implementation in a wide variety of areas of activity. Depending on the tasks set, they are used for:

  • Heating- inside the installations, mechanical energy is converted into thermal energy, due to which the heated liquid moves through the heating system. It should be noted that cavitation heat generators can heat not only industrial facilities, but also entire villages.
  • Heating running water- the cavitation unit is capable of quickly heating a liquid, due to which it can easily replace a gas or electric column.
  • Mixing liquid substances- due to the rarefaction in the layers with the formation of small cavities, such units allow to achieve the proper quality of mixing of liquids, which naturally do not match due to different density.

Advantages and disadvantages

In comparison with other heat generators, cavitation units have a number of advantages and disadvantages.

The advantages of such devices include:

  • Much more efficient mechanism for obtaining thermal energy;
  • Consumes significantly less resources than fuel generators;
  • It can be used for heating both low-power and large consumers;
  • Completely environmentally friendly - does not emit harmful substances into the environment during operation.

The disadvantages of cavitation heat generators include:

  • Relatively large dimensions - electric and fuel models are much smaller, which is important when installed in an already operated room;
  • High noise due to the operation of the water pump and the cavitation element itself, which makes it difficult to install it in household premises;
  • Ineffective ratio of power and performance for rooms with a small square (up to 60m 2 it is more profitable to use a gas installation, liquid fuel or equivalent electric power with heating element). \

DIY CTG

Most simple option for home implementation is a tubular-type cavitation generator with one or more nozzles for heating water. Therefore, we will analyze an example of making just such a device, for this you will need:

  • Pump - for heating, be sure to choose a heat pump that is not afraid of constant exposure to high temperatures. It must provide a working pressure at the outlet of 4 - 12 atm.
  • 2 pressure gauges and sleeves for their installation - located on both sides of the nozzle to measure the pressure at the inlet and outlet of the cavitation element.
  • Thermometer for measuring the amount of heating of the coolant in the system.
  • Valve for removing excess air from the cavitation heat generator. Installed at the highest point of the system.
  • Nozzle - must have a bore diameter from 9 to 16 mm, it is not recommended to do less, since cavitation can occur already in the pump, which will significantly reduce its service life. The shape of the nozzle can be cylindrical, conical or oval, from a practical point of view, any will suit you.
  • Pipes and connecting elements (heating radiators in their absence) are selected in accordance with the task at hand, but the simplest option is plastic pipes for soldering.
  • Automation of turning on / off the cavitation heat generator - as a rule, it is tied up under temperature regime, is set to shutdown at about 80 ° C and to turn on when the decrease is less than 60 ° C. But you can choose the operating mode of the cavitation heat generator yourself.

Rice. 6: diagram of a cavitation heat generator

Before connecting all the elements, it is advisable to draw a diagram of their location on paper, walls or on the floor. Locations must be located away from flammable elements or the latter must be removed at a safe distance from the heating system.

Collect all the elements as you depicted in the diagram and check the tightness without turning on the generator. Then test the cavitation heat generator in the operating mode, a normal rise in the temperature of the liquid is 3 - 5 ° C in one minute.

Every year, the rise in heating prices makes us look for cheaper ways to heat living space in the cold season. This is especially true for those houses and apartments that have a large square. One of these ways of saving is vortex. It has many advantages, as well allows you to save on creation. The simplicity of the design will not make it difficult to collect, even from beginners. Next, we will consider the advantages of this heating method, and also try to draw up a plan for assembling a heat generator with our own hands.

A heat generator is a special device, the main purpose of which is to generate heat by burning the fuel loaded into it. In this case, heat is generated, which is spent on heating the coolant, which in turn directly performs the function of heating the living space.

The first heat generators appeared on the market back in 1856, thanks to the invention of the British physicist Robert Bunsen, who, in the course of a series of experiments, noticed that the heat generated during combustion can be directed in any direction.

Since then, generators, of course, have been modified and are capable of heating much more area than they were 250 years ago.

The principal criterion by which generators differ from each other is the fuel to be charged. Depending on this, they distinguish the following types:

  1. Diesel heat generators - generate heat through combustion diesel fuel... They are capable of heating large areas well, but it is better not to use them for the house due to the production of toxic substances formed as a result of fuel combustion.
  2. Gas heat generators - work on the principle of continuous gas supply, burning in a special chamber that also generates heat. It is considered a very economical option, but the installation requires special permission and increased safety.
  3. Solid fuel generators are similar in design to a conventional coal stove with a combustion chamber, a soot and ash compartment, and a heating element. They are convenient for operation in open areas, since their operation does not depend on weather conditions.
  4. - their principle of operation is based on the process of thermal conversion, in which bubbles formed in the liquid provoke a mixed flow of phases, which increases the amount of heat generated.

Well known classic ways generating electricity have one significant drawback, which is their strong dependence on the source itself. And even the so-called "alternative" approaches that allow you to extract energy from such natural resources, like the wind or the sun's rays, are not devoid of this drawback (see photo below).

In addition, the traditionally used resources (coal, peat and other combustible materials) sooner or later run out, forcing developers to look for new options for obtaining energy. One of these approaches involves the development of a special device, which in the circle of specialists is called a self-powered generator.

Operating principle

It is customary to refer to the category of generators in which self-feeding is used, the following names of original designs, which have recently been increasingly mentioned on the Internet:

  • Various modifications of the Tesla free energy generator;
  • Sources of energy of vacuum and magnetic fields;
  • The so-called "radiant" generators.

Among lovers of non-standard solutions, much attention is paid to the well-known circuit solutions of the great Serbian scientist Nikola Tesla. Inspired by his proposed non-classical approach to using the possibilities of the e / magnetic field (the so-called "free" energy), natural scientists are looking for and finding new solutions.

Known devices, which, according to the generally accepted classification, belong to similar sources, are divided into the following types:

  • The previously mentioned radiant generators and the like;
  • Blocking system complete with permanent magnets or transgenerator (its appearance can be found in the figure below);

  • The so-called "heat pumps" that operate due to temperature differences;
  • Vortex device of special design (another name - Potapov generator);
  • Systems for electrolysis of aqueous solutions without energy pumping.

Of all these devices, the rationale for the principle of operation exists only for heat pumps, which are not generators in the full sense of the word.

Important! The existence of an explanation for the essence of their work is due to the fact that the technology of using the temperature difference has long been used in practice in a number of other developments.

Much more interesting is the acquaintance with the system operating on the principle of radiant transformation.

Overview of radiant generators

Devices of this type work in a similar way to electrostatic converters, with one slight difference. It consists in the fact that the energy received from the outside is not all spent on internal needs, but is partially given back to the supply circuit.

The most well-known radiant energy systems include:

  • Tesla Transmitter Amplifier;
  • Classic SE generator with extension to BTG blocking system;
  • A device named for the inventor T. Henry Morrey.

All new generators coming up by fans alternative ways energy production, are able to work on the same principle as these devices. Let's consider each of them in more detail.

The so-called "transmitter-amplifier" is manufactured in the form of a flat transformer connected to an external energy source by means of an assembly of spark gaps and electrolytic capacitors. Its feature is the ability to generate standing waves of a special form of e / magnetic energy (it is called radiant), which propagates in environment and hardly diminishes with distance.

According to the idea of ​​the inventor himself, such a device was to be used for wireless transmission of electricity over ultra-long distances. Unfortunately, Tesla did not manage to fully implement his plans and experiments, and his calculations and schemes were partially lost, and some were later classified. The diagram of the generator-transmitter is shown in the photo below.

Any copying of Tesla's ideas did not lead to the desired result, and all the installations assembled according to this principle did not provide the required efficiency. The only thing that was achieved in this case was to make a device with a large transformation ratio with our own hands. The assembled product made it possible to obtain a voltage of the order of hundreds of thousands of volts at the output with a minimum amount of electricity supplied to it.

Generators CE (blockings) and Morrey

The work of CE generators is also based on the radiant principle of energy conversion, obtained in the self-oscillation mode and does not require constant pumping. After starting it, recharge is carried out due to the output voltage of the generator itself and the natural magnetic field.

If a self-made product was launched from a battery, then during its operation, the excess energy can be used to recharge this battery (figure below).

One of the varieties of self-powered blocking generators is a transgenerator, which also uses the Earth's magnetic field in its work. The latter affects the windings of its transformer, and this device itself is simple enough so that you can assemble it yourself.

By combining the physical processes observed in CE systems and permanent magnet devices, it is possible to obtain blocking generators (photo below).

Another type of devices considered here belongs to the oldest variants of the free energy generation scheme. This is a Morrey generator, which can be assembled by means of a special circuit with diodes and capacitors connected in a certain way.

Additional Information. At the time of his invention, capacitors in their design resembled the then fashionable electric lamps, however, unlike them, they did not need to heat the electrodes.

Vortex devices

Talking about free sources of electricity, it is imperative to touch upon special systems capable of generating heat with an efficiency of more than 100%. This device refers to the previously mentioned Potapov generator.

Its action is based on the mutual vortex effect of coaxially acting fluid flows. The principle of its operation is well illustrated by the following figure (see photo below).

To create the required water pressure, a centrifugal pump is used, which directs it through the pipe (2). In the course of its spiral motion at the walls of the body (1), the flow reaches the reflecting cone (4) and is divided after it into two independent parts.

In this case, the heated external part of the flow returns back to the pump, and its internal component is reflected from the cone with the formation of a smaller vortex. This new vortex flows through the inner cavity of the primary vortex formation, and then enters the outlet of the branch pipe (3) with the heating system connected to it.

Thus, heat transfer is carried out due to the exchange of vortex energies, and the complete absence of mechanical moving units provides it with a very high efficiency. It is rather difficult to make such a converter with your own hands, since not everyone has special equipment for boring metal.

In modern models of heat generators operating on this principle, attempts are made to use the phenomenon of the so-called "cavitation". It is understood as the process of formation of vaporous air bubbles in a liquid and their subsequent collapse. All this is accompanied by a violent release of a significant amount of thermal substance.

Water electrolysis

In those cases when it comes to electric generators of a new type, one should not forget about such a promising direction as the study of the electrolysis of liquids without the use of third-party sources. The interest in this topic is explained by the fact that water is inherently a natural, reversible source. This follows from the structure of its molecule, which, as you know, contains two hydrogen atoms and one oxygen.

During the electrolysis of the water mass, the corresponding gases are formed, which are used as full-fledged substitutes for traditional hydrocarbons. The fact is that when gaseous compounds interact, a water molecule is again obtained, plus a significant amount of heat is simultaneously released. The difficulty of this method is to ensure that the required amount of energy is supplied to the electrolysis bath, sufficient to support the decomposition reaction.

This can be achieved if you change the shape and location of the electrode contacts used, as well as the composition of a special catalyst with your own hands.

If in this case the possibility of exposure to a magnetic field is taken into account, then it is possible to achieve a significant decrease in the power consumed for electrolysis.

Note! Several similar experiments have already been carried out, proving that, in principle, it is possible to decompose water into components (without additional pumping of energy).

There is little to do - to master the mechanism that collects atoms into a new structure (again synthesizes a water molecule).

Another type of energy conversion is associated with nuclear reactions, which, for obvious reasons, cannot be carried out at home. In addition, they need huge material and energy resources sufficient to initiate the process of nuclear decay.

These reactions are organized in special reactors and accelerators, where conditions with a high magnetic field gradient are created. The problem faced by specialists who are keen on cold fusion of nuclei (CNF) is the search for ways to maintain nuclear reactions without additional supply of external energies.

In conclusion, we note that the problem of the devices and systems discussed above is the presence of strong opposition from corporate forces, whose well-being is based on traditional hydrocarbons and atomic energy. CNF research, in particular, has been declared an erroneous direction, as a result of which all their centralized funding has been completely stopped. Today, the study of the principles of obtaining free energies is supported only by the forces of enthusiasts.

Electric power generation devices can be divided into several categories, depending on what type of energy is used for conversion:

  • thermal;
  • hydraulic;
  • wind;
  • sunny.

All of these devices are currently the main suppliers of electricity. The disadvantage here is the reliance on convertible sources.

Tesla CE Amplifying Transmitter

Disadvantages of energy sources

Thermal power generators use the energy of combustion of coal or oil products, the reserves of which in the earth's interior are coming to an end. Nuclear power plants are of the same type. The reserves of radioactive elements are still quite large, but they are also not infinite. Thermal power plants are the most harmful to the environment. These are emissions of incompletely burned hydrocarbons and carbon dioxide into the atmosphere, as well as a high probability of radioactive contamination (for devices using atomic energy).

Hydraulic devices include hydroelectric power plants that use the energy stored in water reservoirs of rivers and tidal power plants that use the energy of the ebb and flow. The normal operation of hydroelectric power plants depends on the water level in the reservoir and, if it drops significantly, is excluded. In addition, hydroelectric dams have an extremely negative impact on the existing ecosystems of rivers and coastal areas. Tidal power plants have less negative impact on the environment.

Wind generators rely on air movement and can only be built in areas with steady winds. With climate change, the performance of wind generators may be questionable.

The situation is similar with solar energy conversion devices. Solar power plants are installed only in areas with a lot of sunny days a year. Such power plants do not work at night and in cloudy weather.

The listed disadvantages force us to actively search alternative sources energy.

Alternative energy sources

Among the enthusiasts, the most widespread attention is paid to the use of free energy and the Earth's magnetic field. Since there is still no scientific basis for the definition of free energy, there are disputes about what free energy is. Most of the research is carried out in the field of the application of radiant energy, vacuum energy and magnetic field. The source of inspiration for the design of free energy generators with your own hands is the work of the Serbian scientist Nikola Tesla.

All devices that use the principle of free energy in their work are divided into:

  • radiant generators;
  • permanent magnet blocking generators with no moving parts;
  • permanent magnet blocking generators;
  • transgenerator;
  • mechanical heaters with an efficiency greater than one;
  • implosion ( vortex generators Potapova);
  • electrolysis of water without external energy sources;
  • heat pumps;
  • cold nuclear fusion.

Of all the devices listed, only heat pumps have a rigorous scientific basis. More precisely, they are not free energy generators, since they use in their work the temperature difference in different layers of the earth.

Radiant CE generators

Radiant energy is similar to electrostatic energy, which is often confusing. Radiant energy is obtained from the environment or an external source of electricity with the subsequent return to the external circuit of its surplus.

The most famous radiant energy devices are the Tesla amplifying transmitter, the self-powered CE generator, and the T. Henry Morrey generator. All new schemes use their principles of operation in their work.

Tesla Amplifying Transmitter

Tesla's amplifying transmitter is a resonant transformer with special flat-shaped windings, which are powered from an external power source by means of special capacitors and arresters.

A feature of the transmitter is the generation of standing waves of radiant energy in the environment, which does not diminish with distance. The field of application of the amplifying transmitter was assumed to be remote wireless transmission of electricity. Unfortunately, Tesla did not have time to fully complete the experiments on the transfer of energy, and the drawings and descriptions of the experimental installations turned out to be classified after his death. A photo of the receiving and transmitting tower of the Tesla amplifying transmitter is shown above.

Self-assembled, new installations, if they worked, gave out extremely low efficiency. The only device that can be assembled and tested with your own hands is a Tesla transformer, which has a huge transformation ratio and is capable of producing tens and hundreds of thousands of volts at the output at a negligible cost of input electricity.

T. Henry Morrey's generator

The T. Henry Morrey generator is based on the conversion of radiant energy through specially designed capacitors and diodes. Structurally, capacitors were similar to electronic lamps, however, unlike the latter, they did not require additional heating of the electrodes (Fig. Below).

T. Henry Morrey capacitor

The self-energized CE generator is a self-oscillating generator that requires power from an external source to start generation. Subsequently, power is supplied from the generator output voltage under the influence of the Earth's magnetic field. If a self-assembled generator is started from a battery, then when a self-powered blocking generator is operating, excess energy can be used to recharge the battery (Figure below). The operation of the generator is based on the interaction of the magnetic field of the transformer with energy from various sources.

Self-powered CE generator circuit

One of the variants of a self-powered free energy generator is a transgenerator (Fig. Below). This generator uses the action of the Earth's magnetic field on the transformer windings and is very easy to assemble with your own hands.

Scheme of a transgenerator - a free energy generator with self-supply

Free energy generators

By combining the physical processes of self-powered CE generators and permanent magnet generators, a circuit of a permanent magnet magnetic blocking generator is obtained (Fig. Below). Such a blocking generator also requires a pulse from the input source to start generating. Powerful magnets are used here to create a magnetic field.

Schematic of a blocking generator CE on permanent magnets

Implosion (vortex) generators

Speaking about power generators, one cannot fail to mention heat sources that allow you to generate heat with an efficiency of more than 100%. We are talking about vortex generators designed by Yu. S. Potapov. The work of the heat generator is based on the interaction of coaxial vortex flows of liquid. The principle of operation of the Potapov vortex generator is shown in the figure below.

Potapov vortex generator circuit

Water supply is carried out centrifugal pump through the pipe (2). Moving in a spiral along the outer wall of the body (1), the liquid approaches the reflecting cone (4), where it is divided into two streams. The external, heated flow returns to the pump, and the internal, reflected from the surface of the cone, forms a vortex of a smaller diameter, which passes inside the primary vortex and enters the outlet pipe (3), to which the heating system is connected.

Heating of the liquid occurs due to heat exchange between the vortices. The absence of moving parts in the heat exchanger provides the heat generator with ultra-high efficiency.

It is difficult to assemble a Potapov vortex heater with your own hands, since the use of factory equipment for metal processing is required.

New versions of heat generators use the phenomenon of cavitation - the formation of microscopic vapor bubbles in the volume of a liquid and their collapse. This process is accompanied by the release of a large amount of thermal energy.

Water electrolysis

New directions of research are very promising, which deal with the problem of water electrolysis without the use of third-party energy sources. Water is the simplest reversible energy source. Everything is very simple. Water molecules are made up of oxygen and hydrogen atoms. Electrolysis produces oxygen and hydrogen gases that can be used as a replacement for any hydrocarbon fuel.

The interaction of oxygen and hydrogen occurs with the formation of water molecules and the release of a large amount of heat. The problem with electrolysis is the need to supply a large amount of energy for the reaction to proceed. By changing the configuration of the electrodes and the composition of the catalyst, as well as the energy of the magnetic field, it is possible to achieve a significant reduction in power consumption. A number of experiments have already been carried out, which prove the possibility of decomposing water into its constituent elements without supplying energy and creating new sources of energy.

Cold fusion

Traditional nuclear and thermonuclear reactions, during which some elements are converted into others, require a huge amount of energy to initiate the process. This is due to the fact that for the transformation of elements, it is required to bring their nuclei closer to a very small distance, at which the forces of mutual repulsion are so great that they require huge expenditures of energy.

Such reactions take place in atomic reactors, atomic bombs and particle accelerators under conditions of high magnetic field strength.

A nuclear reactor works on the same principle as an atomic bomb, except that the reaction can be controlled. Reactors require specific fuel and are extremely dangerous in terms of radiation contamination and radiation exposure.

The problem of cold nuclear fusion is to find the possibility of carrying out nuclear reactions without the supply of external energy and without the release of radioactive radiation. As with water electrolysis, new research has already shown positive results.

The problem with free energy generators is the active opposition of the proponents of traditional sources, since the entire world economy is based on hydrocarbon fuels and radioactive materials. Cold fusion has been declared a pseudoscience, and all funding in this area has been cut off. All work is carried out by enthusiasts only.

Video. Self-powered generator

There are many links to CE generator designs on the Internet different types such as transgenerator or blocking generator CE. Descriptions and specifications, method of calculations and assembly with your own hands. However, there are no links pointing to where a working prototype of a free energy generator can be seen. Also, many people assembled free energy generators, blocking generators with their own hands, but their characteristics did not correspond to the declared ones, or the devices did not work at all.

Not at all industrial facilities it is possible to heat premises with classical heat generators operating on combustion of gas, liquid or solid fuel, and the use of a heater with heating elements is impractical or unsafe. In such situations, a vortex heat generator comes to the rescue, which uses cavitation processes to heat the working fluid. The basic principles of operation of these devices were discovered back in the 30s of the last century, and have been actively developed since the 50s. But the introduction into the production process of heating a liquid due to vortex effects occurred only in the 90s, when the issue of saving energy resources became most acute.

Device and principle of operation

Initially, due to vortex flows, they learned how to obtain heating of air and other gas mixtures. At that moment, it was not possible to heat water like this due to its lack of compression properties. The first attempts in this direction were made by Merkulov, who proposed filling the Rank pipe with water instead of air. The release of heat turned out side effect vortex motion of the fluid, and long time the process did not even have a rationale.

Today it is known that when a liquid moves through a special chamber, water molecules push out gas molecules from excess pressure, which accumulate in bubbles. Due to the percentage advantage of water, its molecules tend to crush gas inclusions, and the surface pressure in them increases. With the further supply of gas molecules, the temperature inside the inclusions increases, reaching 800 - 1000 ° C. And after reaching the zone with a lower pressure, the process of cavitation (collapse) of bubbles occurs, in which the accumulated thermal energy is released into the surrounding space.

All vortex heat generators are divided into three categories depending on the method of formation of cavitation bubbles inside the liquid:

  • Passive tangential systems;
  • Passive axial systems;
  • Active devices.

Now let's look at each of the categories in more detail.

Passive tangential HTG

These are such vortex heat generators, in which the thermogenerating chamber has a static design. Structurally, such vortex generators represent a chamber with several nozzles through which the coolant is supplied and removed. Excessive pressure in them is created by pumping liquid with a compressor, the shape of the chamber and its content is a straight or swirling pipe. An example of such a device is shown in the figure below.

Picture 1: circuit diagram passive tangential generator

When the liquid moves along the inlet pipe, deceleration occurs at the inlet to the chamber due to the braking device, which results in a rarefied space in the volume expansion zone. Then the bubbles collapse and the water heats up. To obtain vortex energy in passive vortex heat generators, several inlets / outlets from the chamber, nozzles, a variable geometric shape and other techniques are installed to create variable pressure.

Passive axial heat generators

Like the previous type, passive axial ones do not have moving elements to create vortices. Vortex heat generators of this type carry out heating of the coolant by installing a diaphragm with cylindrical, spiral or conical holes in the chamber, a nozzle, a die, a choke acting as a restriction device. In some models, several heating elements are installed with different characteristics of the passage holes to increase their efficiency.


Rice. 2: schematic diagram of a passive axial heat generator

Look at the figure, here is the principle of operation of the simplest axial heat generator. This thermal installation consists of a heating chamber, an inlet that introduces a cold liquid flow, a flow former (not present in all models), a restriction device, an outlet with a hot water flow.

Active heat generators

Heating of a liquid in such vortex heat generators is carried out due to the operation of an active movable element interacting with a coolant. They are equipped with cavitation-type chambers with disk or drum activators. These are rotary heat generators, one of the most famous among them is the Potapov heat generator. The simplest diagram of an active heat generator is shown in the figure below.


Rice. 3: schematic diagram of an active heat source

When the activator rotates in this, bubbles are formed due to holes on the surface of the activator and multidirectional with them on the opposite wall of the chamber. This design is considered the most effective, but also quite complex in the selection of the geometric parameters of the elements. Therefore, the majority of vortex heat generators have perforations only on the activator.

Appointment

At the dawn of the introduction of the cavitation generator into operation, it was used only for its intended purpose - for the transfer of thermal energy. Today, in connection with the development and improvement of this direction, vortex heat generators are used for:

  • Heating of premises, both in domestic and industrial areas;
  • Heating liquid for technological operations;
  • As instantaneous water heaters, but with a higher efficiency than classic boilers;
  • For pasteurization and homogenization of food and pharmaceutical mixtures with a set temperature (this ensures the removal of viruses and bacteria from the liquid without heat treatment);
  • Obtaining a cold stream (in such models, hot water is a side effect);
  • Mixing and separation of petroleum products, adding chemical elements to the resulting mixture;
  • Steam generation.

With the further improvement of vortex heat generators, the scope of their application will expand. Moreover, this type of heating equipment has a number of prerequisites for ousting the still competitive technologies of the past.

Advantages and disadvantages

In comparison with identical technologies designed for heating rooms or heating liquids, vortex heat generators have a number of significant advantages:

  • Environmental friendliness- in comparison with gas, solid fuel and diesel heat generators, they do not pollute the environment;
  • Fire and explosion safety- vortex models, in comparison with gas heat generators and devices for oil products, do not pose such a threat;
  • Variability- vortex heat generator can be installed in existing systems without the need to install new pipelines;
  • Economy- in certain situations, it is much more profitable than classical heat generators, since they provide the same thermal power in terms of the consumed electrical power;
  • No cooling system required;
  • Does not require the organization of the removal of combustion products do not emit carbon monoxide and do not pollute the air of the working area or living quarters;
  • Provide a sufficiently high efficiency- about 91 - 92% with a relatively low power of the electric motor or pump;
  • Scale does not form when the liquid is heated, which greatly reduces the likelihood of damage due to corrosion and clogging with limescale;

But, in addition to the advantages, vortex heat generators also have a number of disadvantages:

  • Creates a strong noise load at the installation site, which greatly limits their use directly in bedrooms, halls, offices and similar places;
  • Characterized by large dimensions, in comparison with classic liquid heaters;
  • Requires fine tuning of the cavitation process, since bubbles, when colliding with the walls of the pipeline and the working elements of the pump, lead to their rapid wear;
  • Fairly expensive repair in case of failure of the elements of the vortex heat generator.

Criterias of choice

When choosing a vortex heat generator, it is important to determine the actual parameters of the device, which are most suitable for solving the task at hand. These parameters include:

  • Power consumption- determines the amount of electricity consumed from the network, required for the operation of the installation.
  • Conversion factor- determines the ratio of consumed energy in kW and released as heat energy in kW.
  • Flow rate- determines the speed of movement of the liquid and the possibility of its regulation (allows you to regulate the heat exchange in heating systems or the pressure in the water heater).
  • Vortex chamber type- determines the method of obtaining heat energy, the efficiency of the process and the costs required for this.
  • dimensions- an important factor affecting the possibility of installing a heat generator in any place.
  • Number of circulation circuits- some models, in addition to the heating circuit, have a cold water drainage circuit.

The parameters of some vortex heat generators are given in the table below:

Also, an important factor is the price of a vortex heat generator, which is set by the manufacturer and can depend on both design features, and on the parameters of work.
