STEAM-GAS INSTALLATION Russian patent published in 2010 - IPC F01K23/10 

FIELD: power industry.

SUBSTANCE: steam-gas installation (SGI) consists of gas-turbine assembly, of steam boiler-utiliser (BU) and two-cylinder steam turbine with condenser. The gas-turbine assembly is equipped with at least one gas turbine, a combustion chamber and with at least one compressor mounted on a shaft of the gas turbine. At the steam inlet of the first cylinder the two-cylinder steam turbine with the condenser is communicated with the steam outlet of BU, at the outlet of the second cylinder it is communicated with the steam inlet of the condenser. At the condensate outlet the condenser is hydraulically tied with the condensate inlet of BU. SGI is also equipped with an additional double-stage compressor, which at the first stage air inlet is communicated with atmospheric air, at the second stage air outlet - with the air outlet of one of the compressors of the gas-turbine assembly. Also the first stage of the additional compressor is installed on one separate shaft with the second cylinder of the steam turbine, while its second stage - on one separate shaft with the first cylinder of the steam turbine.

EFFECT: increased heat drop in steam turbine without implementation of reducer, and, in total, increased efficiency of steam turbine installation in all operation range of loads.
