Description

The invention relates to the field of power engineering and can be used for autonomous supply of thermal energy to residential and industrial facilities.

A known heat supply system containing a device for producing a coolant in the form of a gas mixture with means for spraying water into the stock of fuel combustion products, a device for supplying fuel and a gas duct

/ a.s USSR No. 989233, F24H 1/10, 01/15/1983 / [1].

A disadvantage of the known heat supply system is a complex, bulky design that uses oil fuel in operation, which is not economically efficient and environmentally hazardous.

The closest in technical essence to the present invention is a contact water heater containing a burner with a water jacket and electrodes in the cavity, a water supply device, a device for supplying a mixture of electrolyte and fuel to the burner, a container on which a burner is installed that utilizes the heat generated by the burner, and a heat consumer energy

/ Magazine "Inventor and Rationalizer", 6/2007, p.5. / [2].

The disadvantage of the closest analogue is the complexity of the design, low efficiency of the burner due to the difficulty of matching combustion and water supply to her jacket.

The technical problem solved by the invention is to increase the effective performance of the device while simplifying its design.

The problem is solved in that a steam-gas mixture generator containing a blank bottom housing, a burner, catalyst electrodes, a nozzle with a cavitator, a device for supplying and spraying water into the cavity of the body and a device for feeding and spraying a mixture of an electrolyte / aqueous electrolyte solution / and fuel through a nozzle with a cavitator in the cavity of the burner, while the burner is installed in the cavity of the casing and has a dull bottom, the electrodes-catalysts are configured to supply direct current to them, ignition and quench the volt / electric arc / arc and are installed in the cavity of the burner, and one of the electrodes has the form of a nozzle with a conical channel.

Said feed and spraying devices are made adjustable, for example, by a control unit. One of the mentioned catalyst electrodes, having the form of a nozzle with a conical channel, is made installed in the burner with the possibility of dividing its cavity into a combustion zone and a mixing zone, and the mixing zone of the burner is communicated with openings to the housing cavity and the pipe is in communication with the consumer of the gas-vapor mixture. In this case, the second electrode-catalyst can be made movable, for example, a deflectable electromagnet, when igniting a volt arc.

The invention is schematically shown in the drawing.

An example of the implementation of the proposed solution.

The gas-vapor mixture generator contains a housing 1 with a blind bottom, in the cavity 2 of which a burner 3 with a blind bottom is installed, having electrodes-catalysts 4 and 5, for example, sprayed with platinum black with the possibility of applying direct current to them, igniting and extinguishing a volt / electric / arc installed in its cavity, while one of the electrode-catalysts has the form of a nozzle with a conical channel 6 and is installed in the burner so that it divides the cavity into the combustion zone 7 and into the mixing zone 8, where the mixing zone is connected with openings 9 with the cavity whisker and nozzle 10 communicates with the user 11 the gas-vapor mixture. In this case, the second electrode-catalyst can be made movable, for example, a deflectable electromagnet 12, when igniting a volt arc.

The generator also contains a device, for example a nozzle 13, controlled, say, by a control unit for supplying and spraying water into the body cavity, and a device also controlled by a control unit for supplying and spraying a mixture of an electrolyte, for example, an aqueous solution of potassium hydroxide and fuel, for example ethyl alcohol, through nozzle 14 with a cavitator, for example, local narrowing of its channel (not shown) into the cavity of the burner.

The gas-vapor mixture generator operates as follows.

To start the generator in operation, direct current is applied to the electrodes-catalysts 4 and 5, and by briefly turning on the electromagnet 12, the end of the electrode 4 is touched by the electrode 5 and a volt arc is ignited in its conical channel 6. After that, the device for feeding the mixture through the nozzle 14 with a cavitator, for example, local narrowing of its channel / not shown /, and under the control of the control unit into the combustion zone 7 of the burner 3, for example, at a pressure of 6 atm, an electrolyte mixture, for example, an aqueous solution of caustic potassium is fed and sprayed and fuels, such as ethyl alcohol. In the cavitator of the nozzle 14, the mixture partially dissociates, ionizes due to cavitation, and its droplets are finest sprayed. Then the mixture, cooling the electrodes-catalysts 4 and 5, turns into steam, due to the flow of direct current through the electrolyte it is still dissociated, ionized, and the dissociation reaction is accelerated by the presence of a catalyst.

After this, the mixture enters the combustion zone of the voltaic arc and, under its influence, finally dissociates, ionizes, ignites and turns into a plasma, and from the combustion zone 7 through the nozzle of the electrode 5 enters the mixing zone 8 of burner 3. Then into the cavity 2 of the housing 1 with a blind bottom for example, through the nozzle 13 also under pure pressure and under the control of the control unit, pure natural water is supplied and sprayed. This water cools the walls of the burner 3, it itself turns into steam and enters the mixing zone 8 through the openings 9, and, mixed with the high-temperature plasma emerging from the combustion zone 7, normalizes its temperature to a temperature value acceptable to the consumer 11. Then, the resulting vapor-gas mixture through the pipe 10 and, for example, under a pressure of 6 atm is supplied to the consumer 11 and used by him.

To stop the generator, turn off the DC supply to the electrodes-catalysts 4 and 5, stop the flow of the mixture of electrolyte and fuel into the cavity of the burner 3 and water into the cavity of the housing 1.

The proposed gas-vapor mixture generator is structurally simple, highly efficient in operation and environmentally absolutely safe. It can be widely used to supply thermal energy to residential and industrial facilities.
