METHOD FOR OPERATION OF GAS-TURBINE PLANT Russian patent published in 2000 - IPC

FIELD: gas-turbine plants, applicable in production of ground power units for generation of electric power and heat with a high efficiency and at high ecological indicators. SUBSTANCE: turbo-expander 4 combined in shaft with a gas-turbine plant operates on high-pressure air fed from self-contained air compressor 5. Air cooled down as compared with atmospheric air past turbo-expander 4 is fed to inlet 3 of the air compressor of gas-turbine plant 1. Powers of gas- turbine plant 1 and turbo-expander 4 are transmitted to electric generator 3, and high-pressure air heat - to system 8 through heat exchanger 6. EFFECT: enhanced efficiency, reliability, expanded range of application of the gas-turbine plant. 1 cl, 1 dwg
