POWER PLANT FOR HEAT GENERATION WITH PLASMA CHEMICAL REACTIONS WITH AFTERBURNING Russian patent published in 2011 - IPC F22G1/16 F02C6/04 F24J3/00 H05H1/46 C01B3/04 

FIELD: power industry.

SUBSTANCE: power plant for heat generation with plasma chemical reactions with afterburning includes tight closed circuit consisting of two parallel tubes: discharge tube and return tube, which are connected on ends with double elbows. Turbocompressor is installed in discharge pipeline; venturi nozzle block with grid for return flame extinction, chamber of irradiation with high-frequency radio field of gas mixture circulating in closed tight circuit is installed after compressor. Catalyst-afterburner - grid assembled of tubular electric heaters the outer surface of which is coated with thin catalyst layer is installed before gas turbine. Steam-gas turbine at the outlet of which the straightener is installed is arranged after catalyst-afterburner. The following is installed after straightener: gas mixture cooler after turbine and the second catalyst-afterburner. Then, heat exchangers are installed after them: superheater made of plain tube banks, economiser-evaporator section made of finned tube banks. All tube banks have headers. Heat exchangers are connected as per multiple forced circulation diagram. Arrangement of pipelines and gate valves on them allows assembling once-through circuit. In order to start-up and maintain the serviceability of power unit, the following units connected via pipelines to closed circuit are used: units of treatment, make-up and blowdown with saturated steam and carbon dioxide. At operation the power plant requires no constant supply of water vapour and carbon dioxide to closed circuit - it is periodic make-up which is required, as well as no exhaust of combustion products to environment is required.

EFFECT: heat energy generated with power plant can be used both in stationary and transport power systems, both for individual and parallel operation.
