FIELD: power engineering; developing and updating binary combined-cycle plants.
SUBSTANCE: proposed combined-cycle plant has low-pressure compressor 1, air intercooler 2, high-pressure compressor 3, combustion chamber 4, gas turbine 5, exhaust-heat boiler 6, steam turbine 7, and power generator 8. High- and low-pressure compressor stages are chosen to ensure high-pressure compressor pressure ratio corresponding to that found from formula 
proceeding from desired total efficiency of combined-cycle plant.
EFFECT: enhanced efficiency of intercooled binary combined-cycle plant due to optimal proportion of high- and low-pressure compressor stages.
