METHOD OF CHEMICAL REGENERATION OF HEAT OF EXHAUST GASES OF POWER PLANT Russian patent published in 1994 - IPC

FIELD: heat power engineering. SUBSTANCE: exhaust gases flow out from combustion chamber 6, do a work in turbine 7, enter regenerative heat exchangers 4,5 wherein fuel and oxidizer is heated immediate upstream of combustion chamber 6, and then enter a heat exchanger which heats a chemical reactor. Fuel is evaporated and decomposed catalytically within the reactor. The heat exchanger and chemical reactor can be combined if, e. g. a catalyzer is applied on inner surface of a common regenerative heat exchanger from the side of supplying hydrocarbon fuel. Fuel is decomposed under the action of a pressure which exceeds the atmospheric pressure. In so doing a work which is done with fluid pump 1 for increasing pressure is negligibly small with respect to a work on compressing vapor-gas with compressor 3. EFFECT: enhanced efficiency. 5 cl, 1 dwg
