Operation principles of gas turbine generator

Abstract

A method of operating gas turbine generator by mixing air with the cooled recirculating combustion gases, compressing of fuel and air mixture at the cooled recirculating combustion gases, combustion chamber pressurized fuel in the medium obtained compression mixture with the cooled air recirculated products of combustion to form a high-temperature gaseous combustion products, gas turbine decompression formed high temperature to obtain combustion products and the separation into two streams decompression uncooled combustion gas feed stream in a gas duct of the boiler, and the other in a flue recycled gaseous products of combustion to cool and mix with atmospheric air before compression, characterized in that the air before compression is cooled, and cooling the recirculating flue gas and air produces generated in turbo-expander and circulating in a closed circuit with refrigerant.
