Abstract

The thermodynamics analysis of polytropic subatmospheric cycle of gas turbine unit (GTU) with Maisotsenko heat and mass exchanger is executed. Being based on this analysis was obtained technical and economic characteristics of polytropic cycle and conducted their comparing with characteristics of adiabatic cycle. It is shown that for the temperature of steamair mixture at turbine inlet of 340 °С the thermal efficiency of polytropic cycle decreases in relation to an adiabatic cycle on 12,4...5,2 % at the change of air temperature after a sunny heater from 40 to 90 °С. The thermal efficiency of polytropic cycle is reached to 72 percent.
