A supercharging system for a gas turbine system is provided supercharging system having a fan mechanically coupled to the turbine shaft of the turbine system. A bypass subsystem is provided or optionally conveying a portion of the airstream output to other uses. The supercharging system may also be used in conjunction with a combined cycle power system and a bypass subsystem optionally conveys a portion of the airstream output to a heat recovery steam generator.

Gas turbine compressor inlet pressurization and flow control system

A system for reducing emissions includes a gas production source that produces nitrogen oxides, sulfur oxides, hydrogen sulfide, sulfuric acid, nitric acid, formaldehyde, benzene, metal oxides, or volatile organic compound emissions. An exhaust plenum is downstream from the gas production source, and structure for dispersing a solvent is in the exhaust plenum. A collection tank is in fluid communication with the exhaust plenum to receive the solvent from the exhaust plenum, and a heat source is in the exhaust plenum downstream from the structure for dispersing the solvent. A method for reducing emissions from a gas production source includes flowing exhaust gases through an exhaust plenum, dispersing a solvent through a nozzle in the exhaust plenum, collecting the dispersed solvent in a collection tank, and heating the exhaust gases flowing through the exhaust plenum downstream from the nozzle.

System and method for reducing emissions via solvent injection

A system includes a gas production source configured to produce a gas stream comprising nitrogen oxides (NO) and a hydrocarbon injector disposed downstream of the gas production source and configured to inject a hydrocarbon into the gas stream. The hydrocarbon is configured to oxidize molecules of the NOin the gas stream to produce a higher order compound of nitrogen and oxygen (NO). The system also includes a removal device disposed downstream of the hydrocarbon injector. The removal device is configured to remove the NOfrom the gas stream via absorption or reaction.

[object Object]

A flame-holding control method in a gas turbine having a combustor can and a fuel nozzle disposed in the combustor can. The method can include performing a first scheduled injection of a diluent stream into the nozzle, checking to see if a time period has exceeded a time threshold and in response to the time period being greater than that the time threshold, performing a second scheduled injection of the diluent stream into the nozzle.

Automatic fuel nozzle flame-holding quench

A method of protecting a turbine compressor of a gas turbine engine that is part of an integrated gasification combined-cycle power generation system that includes an air separation unit that may include the steps of: (1) extracting an amount of compressed air that is compressed by the turbine compressor; (2) supplying the extracted amount of compressed air to the air separation unit; and (3) varying the amount of compressed air extracted from the turbine compressor based upon a desired compressor pressure ratio across the turbine compressor. The method further may include the step of supplying the air separation unit with a supply of compressed air from a main air compressor. The amount of compressed air supplied to the air separation unit by the main air compressor may be varied based upon the amount of compressed air extracted from the turbine compressor.

Methods and systems of variable extraction for compressor protection

A method of controlling a load of a gas turbine engine that is part of an integrated gasification combined-cycle power generation system, which includes an air separation unit, that includes the steps of: (1) extracting an amount of compressed air that is compressed by a turbine compressor; (2) supplying the extracted amount of compressed air to the air separation unit; and (3) varying the amount of compressed air extracted from the turbine compressor based upon a desired load for the gas turbine engine.
