FIELD: engines and pumps.
SUBSTANCE: system of gas-turbine engine with recuperation that applies catalytic combustion comprises compressor, fuel system, catalytic combustion chamber, compressor-driving turbine. Recuperator is designed for collection of exhaust gases from turbine as well as mixture exhausted from compressor. In recuperator mixture is heated upstream inlet of catalytic combustion chamber. Gas-turbine engine also comprises system for direction of some exhaust gases from turbine into compressor so that temperature of mixture exhausted from compressor is increased by means of specified exhaust gases, and as a result, temperature at the inlet to catalytic combustion chamber also increases.
EFFECT: temperature control at the inlet to combustion chamber.
