GAS TURBINE PLANT Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: gas turbine plant has turbine with combustion chamber and regenerator installed on exhaust branch pipe. Regenerator is made in form of housing accommodating process line shifting tandem-mounted capsules with heatable working medium in direction opposite to direction of flow of preheated working medium in combustion chamber. Auxiliary regenerating circuit introduced into gas turbine plant has heat exchanger- cooler of turbine working medium, heat exchanger- heater of turbine working medium, auxiliary turbine, auxiliary turbine compressor and compressor driving engine. Combustion chamber is installed on exhaust branch pipe after heat exchanger- heater. First input of heat exchanger-cooler is connected with first output of regenerator cooled working medium. First output of heat exchanger-cooler is connected with second input of regenerator. Second input of heat exchanger-cooler is connected with exhaust branch pipe of auxiliary turbine. Second output of heat exchanger- cooler is connected with suction branch pipe of auxiliary turbine compressor. Delivery branch pipe of compressor is connected with second input of heat exchanger-heater. Second output of heat exchanger-heater is connected with input branch pipe of auxiliary turbine. First input of heat exchanger-heater is connected with output branch pipe of turbine. First output of heat exchanger-heater is connected with combustion chamber input. Output of combustion chamber is connected with first input of regenerator. First output of heat exchanger-cooler is connected with second input of regenerator. Second output of regenerator is connected with turbine input branch pipe. EFFECT: increased efficiency and economy of plant owing to complete regeneration of heat of effluent gases. 4 cl, 2 dwg
