METHOD FOR REMOVING ENTRAPPED GAS IN POWER PRODUCTION SYSTEM WITH COMBINED CYCLE Russian patent published in 2015 - IPC F02C3/30 F02C6/18 

FIELD: power industry.

SUBSTANCE: power production system with a combined cycle includes a steam-turbine system, a gas-turbine system including a compressor, a combustion chamber and a gas turbine; a heat recovery steam generator, and a flow-through line. A heat recovery steam generator is connected between the gas-turbine system and the steam-turbine system for generation of steam with heat energy taken from the gas-turbine system. The heat recovery steam generator includes the first stage having a possibility of high pressure steam output, the second stage having a possibility of intermediate pressure output, and the third stage having a possibility of low pressure output. The flow-through line has a possibility of passage of the saturated steam generated in the heat recovery steam generator to a combustion chamber of the gas-turbine system. The flow-through line includes a condenser and a superheater. The condenser is connected between the heat recovery steam generator and the superheater, and the superheater is connected between the condenser and the combustion chamber. The condenser is located in the power production system with a combined cycle with non-horizontal orientation so that upward movement of saturated steam from the heat recovery steam generator to the combustion chamber and gravitational downward movement of the condensate formed in the condenser to the heat recovery steam generator is performed with reduction of amount of steam transferred to the combustion chamber at transfer of carbon dioxide from the flow-through line to the combustion chamber.

EFFECT: invention is aimed at reduction of hazardous emissions of components occurring in power production processes.
