POWER PLANT Russian patent published in 2006 - IPC F01K21/04 

FIELD: heat power engineering.

SUBSTANCE: in proposed gas-turbine power plant with air takeoff after compressor and subsequent heating of air by exhaust gases and expansion in free air turbine, water is used as additional working medium which is converted into superheated steam by energy of exhaust gases, including air getting out of air turbine whose temperature is not less than 170°C. power plant has low parameters of working process: compression ratio in compressor less than 12; gas temperature before turbine less than 1400 K; water flow rate less than 9% of air flow rate at effective efficiency of 45-50%. Invention makes it possible to generate, in additional to electric energy, which is equal to approximately 50%, heat energy in form heated water (approximately 30%) and air (approximately 10%). Hot air is clean and it can be used in air conditioning systems and for heating of living rooms.

EFFECT: enlarged operating capabilities.
