An example of the implementation of the proposed solution.

The transport gas-steam power plant comprises a reactor 1, made in the form of a combustion chamber of a gas turbine engine, where the casing 2 forms a cavity 3 in which a flame tube 4 is installed, having a mixing zone 5, through holes 6 communicating with the cavity of the casing. Moreover, the front part 7 of the casing and the front part 8 of the flame tube are sealed. Nozzle 9 supply and spraying of natural water into the cavity of the casing. A nozzle 10 with a cavitator, for example a local narrowing of its channel (not shown), supplying and spraying a mixture of an aqueous solution of electrolyte and fuel, for example methyl alcohol, into the sealed front part of the flame tube. An igniter device made in the form of catalyst electrodes, for example, a cathode 11 and anode 12, sprayed with platinum black, with the possibility of supplying them with direct current, ignition and extinguishing a volt / electric / arc, the electrodes being installed in the sealed front of the flame tube and one of they are made movable, for example, by an electromagnet 13 when igniting a volt arc. The other electrode is conical in shape and with a cone channel 14, while the combustion zone of the mixture of electrolyte and fuel is made in a cone channel, where the mixture dissociates into hydrogen and oxygen under the influence of a voltaic arc, ionizes and turns into plasma. The power plant also contains communicated with the reactor through the pipe 15 and the valve 16 of the gas-steam engine 16, for example a piston.

Transport gas-steam power plant operates as follows.

To start the power plant, electrodes-catalysts 11 and 12 are supplied with a direct current regulated, for example, by a control unit. Then, an electromagnet 13 is turned on and a short-term contact by the end of the electrode 11 being moved moves the anode 12 in its conical channel 14 to ignite a volt / electric / arc. Then, through the nozzle 10 with a cavitator / not shown / into the sealed front part 8 of the flame tube 4, a mixture of an electrolyte, for example, an aqueous solution of caustic potassium, and fuel, is fed and sprayed under the control of the control unit and under excessive pressure, for example, 3 MPa for example 5% methyl alcohol per dose of electrolyte. The supplied mixture due to cavitation in the cavitator of the nozzle 10 partially dissociates, ionizes, its droplets are finest atomized and, cooling the front part 8 of the flame tube 4 and the electrode electrodes, turns into steam. In the process, water from the mixture is still partially dissociated due to the flow of direct current through the electrolyte / cathode 11, anode 12 /, and the dissociation reaction is accelerated by the presence of a catalyst. Then the mixture enters and passes through the combustion zone of the voltaic arc in the cone channel 14 of the electrode 12 and, under the influence of the burning voltaic arc, the mixture finally dissociates into hydrogen and oxygen, ionizes, ignites, turns into plasma and, as if from a nozzle, enters the mixing zone 5 of the flame tube four.

Pure natural water is supplied and sprayed into the cavity 3, sealed by the front part 7 of the casing 2 of the reactor 1 through the nozzle 9 under the overpressure of 3 MPa and under the control of the control unit. This water cools the walls of the flame tube 4, it itself turns into water vapor and then through the holes 6 in the walls of the flame tube 4 enters its mixing zone 5 and blows the cone-shaped electrode 12, isolates and protects the walls of the flame tube 4 from those leaving the combustion zone 14 high-temperature / about 600 ° C / combustion products of the mixture - the plasma and, mixing with this plasma, normalizes its temperature to an acceptable value for the engine 17. Further, the working fluid thus obtained in the reactor 1 with an overpressure of 3 MPa through the pipe 15 enters the spool 16, for example, of the piston engine 17 and, expanding in it, does the job. Spent products in the engine 17 either directly or through a condenser - heat exchanger are thrown into the environment.

To stop the reactor 1, stop supplying direct current to the electrodes 11 and 12, stop the flow of the mixture of electrolyte and fuel through the nozzle 10 and stop the flow of water through the nozzle 9.

The proposed power plant has a simple design for manufacturing and for control during operation, highly economical and environmentally friendly. Will find application in engine building for vehicles and for energy.
