SOLAR-HEAT GAS-TURBINE ENGINE OPERATING PROCESS Russian patent published in 2001 - IPC

FIELD: power engineering; heat and power generation. SUBSTANCE: processes occurring in the course of operation of gas-turbine engine include air compression in compressor, its combustion together with fuel in combustion chamber, expansion in gas turbine, and electric power generation in generator. Amount of heat supplied by fuel injector to combustion chamber (Q_cc) equals that passed to gas-water heat exchanger (Q₄); air compression efficiency η_com= 0,85; gas expansion efficiency . Thermal efficiency of solar-heat gas-turbine engine in terms of thermal power station efficiency η_ths= 0,4. EFFECT: enhanced efficiency of gas-turbine engine. 1 dwg
