FLUID MEDIUM HEATER Russian patent published in 2012 - IPC F24H8/00 

FIELD: power engineering.

SUBSTANCE: fluid medium heater comprises a steam generator, a supercharging unit, a steam turbine and a feed water pump with a drive. The supercharging unit comprises a gas turbine and a coupled air compressor via a shaft, besides, the compressor's inlet is connected to atmosphere. The heater additionally comprises a condenser, a heat exchanger, a valve and a shaft-turbine engine. The engine comprises a compressor, a gas turbine that connects their transmissions, for instance, a shaft and a combustion chamber equipped with inlets for supply of fuel, air, water vapour and outlet of hot gas. The air supply inlet is connected to the outlet of the engine's compressor. The water vapour supply inlet is connected to the outlet of the steam turbine. The outlet of hot gas is connected to the inlet of the engine's gas turbine. The steam generator has channels of cold and hot coolants with inlets and outlets. The condenser has channels of cold and hot coolant with inlets and outlets, and also a separate outlet for condensate drain. The heat exchanger has channels of cold and hot coolant with inlets and outlets. The supercharging unit turbine has an outlet for gas and an outlet for condensate, at the same time the outlet for condensate is connected directly to atmosphere, and the outlet for gas is connected to atmosphere via a cold heat exchanger's circuit.

EFFECT: invention makes it possible to increase efficiency of the heater by utilisation of hidden heat from condensation of water vapour contained in combustion products, to remove a part of nitrogen oxides from waste gases and to reduce temperature of gases in the combustion chamber.
