A turbine system includes a valve coupled to a leak off line from a leak packing of a first turbine, the valve controlling a first steam flow used to maintain a constant self-sustaining sealing pressure to a second turbine across numerous loading conditions. A related method is also provided.

Turbine system including valve for leak off line for controlling seal steam flow

A turbine system is provided wherein during self-sealing operating conditions, excess leakoff steam is restricted from being dumped to a steam seal header and is diverted into the working steam flow path, hence increasing net output and efficiency for the turbine system. A related method is also provided.

System and method for controlling leak steam to steam seal header for improving steam turbine performance

The present application thus provides an integrated gasification combined cycle system. The integrated gasification combined cycle system may include a water gas shift reactor system and a heat recovery steam generator. The water gas shift reactor system may include a recirculation system with a recirculation heat exchanger to heat a flow of syngas. The heat recovery steam generator may include a diverted water flow in communication with the recirculation heat exchanger.

Water gas shift reactor system for integrated gasification combined cycle power generation systems

In a system involving COcapture having an acid gas removal system to selectively remove COfrom shifted syngas, the acid gas removal system including at least one stage, e.g. a flash tank, for COremoval from an input stream of dissolved carbon dioxide in physical solvent, the method of recovering COin the acid gas removal system including: elevating a pressure of the stream of dissolved carbon dioxide in physical solvent; and elevating the temperature of the pressurized stream upstream of at least one COremoval stage.

A combined cycle power plant includes a gas turbine having a first compressor, a second compressor downstream of the first compressor, and a regenerative heat exchanger between the first and second compressors. A steam generator is downstream of the gas turbine and receives exhaust from the gas turbine. A closed loop cooling system through the regenerative heat exchanger and the steam generator transfers heat from the regenerative heat exchanger to the steam generator. A method for operating a combined cycle power plant includes compressing a working fluid in a compressor and cooling the compressed working fluid with a regenerative heat exchanger so as to create a cooled compressed working fluid. The method further includes transferring heat from the regenerative heat exchanger to a steam generator.
