COMBINED GAS TURBINE PLANT (VERSIONS) Russian patent published in 2009 - IPC F02C6/18 F02C7/08 

FIELD: engines and pumps.

SUBSTANCE: proposed plant comprises multi-stage compressor stages with intermediate air coolers arranged there between, combustion chamber, gas turbine, steam loop with exhaust heat boiler and steam turbine connected with its electric generator. Regenerator cooled medium outlet is connected to gas turbine outlet, while regenerator heated medium outlet is connected to last stage of multi-stage compressor and combustion chamber inlet. Proposed plant comprises also absorption refrigerating machine and residual heat recovery unit with its inlet communicated with absorption refrigerator outlet and its outlet communicating with exhaust heat boiler. Steam loop is furnished with blower connected with regenerator outlet. Circulation coolant of absorption refrigerator is connected to intermediate air coolers, while its heat sensitive elements are connected, in compliance with first version, with steam turbine outlet. In compliance with second version, combines gas turbine plant incorporates Stirling engine instead of steam turbine. Heat sensitive elements of aforesaid absorption refrigerant are connected to Stirling engine hot chamber. Gas turbine is connected to electric generator and/or gas-compressor plant drive.

EFFECT: higher efficiency, reduced exhaust of toxic substances.
