REGENERATIVE GAS-TURBINE INSTALLATION Russian patent published in 2011 - IPC F02C7/10 

FIELD: machine building.

SUBSTANCE: regenerative gas-turbine installation consists of low pressure compressor, of air duct of low pressure, of intermediate air cooler, of compressor of high pressure, of air duct of high pressure, of regenerator of high pressure, of high pressure combustion chamber, of a duct of high pressure, of gas turbine of high pressure, of power gas turbine, of drive unit, for, example, electro-generator, and of exhaust gas duct of high pressure gas turbine. An outlet of the low pressure compressor is connected with the compressor of high pressure by means of the air duct of low pressure via the intermediate air cooler. The high pressure compressor is coupled with the high pressure gas turbine via the high pressure air duct, an air side of the regenerator of high pressure, the high pressure combustion chamber and the gas duct of high pressure. An outlet of the high pressure gas turbine is connected with atmosphere through the exhaust gas duct of the high pressure gas turbine and a gas side of the regenerator of high pressure. A rotor of the power gas turbine is connected with the drive unit by means of a shaft. The rotor of the high pressure gas turbine is connected with rotors of the low pressure compressor and the high pressure compressor with the common shaft. The regenerative gas-turbine installation is equipped with an additional air duct of low pressure, with the regenerator of low pressure, with low pressure combustion chamber, with the low pressure gas duct, with the exhaust gas duct of the power gas turbine, and with a common exhaust gas duct of the installation. By means of an additional air duct of low pressure the outlet of the intermediate air cooler is connected with the power gas turbine through the regenerator of low pressure, the low pressure combustion chamber and the gas duct of low pressure. The exhaust gas duct of the gas turbine of high pressure is united with the exhaust gas duct of the power gas turbine by means of a common exhaust gas duct of the installation. The common exhaust gas duct of the installation is connected with atmosphere through gas sides of the regenerator of high pressure and regenerator of low pressure successively connected to it. The rotor of the power gas turbine is connected with the drive unit, for example, with the electro-generator, by means of a common shaft.

EFFECT: raised heat efficiency of regenerative gas-turbine installation.
