Abstract:

A system includes a compressor having a compressor inlet, a turbine having a plurality of stages disposed within a turbine casing, and a turbine extraction gas (TEG) heating system. The turbine is configured to drive the compressor via expansion of combustion products through the plurality of stages. The TEG heating system includes a turbine gas extraction system coupled to the turbine casing and to the compressor inlet. The turbine gas extraction system is configured to receive a portion of the combustion products as a turbine extraction gas (TEG) from the turbine. The TEG is received through the turbine casing, the TEG heating system is configured to supply a heated flow to the compressor inlet, and the heated flow includes the TEG.

International Classification:

F02C 7/08

Abstract:

A system includes a controller configured to control a heated flow discharged from an outlet of a mixing chamber to an inlet control system to control a temperature of an intake flow through a compressor inlet of a compressor of a gas turbine system. The controller is configured to control a turbine extraction gas (TEG) flow to the mixing chamber. The controller is configured to control at least one of a pressurized flow of the compressor to the mixing chamber and a steam flow to the mixing chamber. The TEG flow is extracted through a turbine casing. The heated flow includes the TEG flow and the at least one of the pressurized flow and the steam flow.
