Appl. No.:

13/217646

Inventors:

Noémie Dion Ouellet - Greenville SC, US
Daniel David Snook - Greenville SC, US
Lisa Anne Wichmann - Greenville SC, US
Samuel David Draper - Greenville SC, US
Scott Allen Rittenhouse - Columbus IN, US

Assignee:

General Electric Company - Schenectady NY

International Classification:

F02C 7/08
F02C 6/00
F02C 6/04
F02G 1/00
F02G 3/00

US Classification:

60 3952, 60 39182, 60785

Abstract:

Ambient air is compressed into a compressed ambient gas flow and delivered to a turbine combustor. At least one of an exhaust port, a bypass conduit, or an extraction conduit is opened to vent the power plant. A turbine shaft is rotated at an ignition speed and a fuel stream is delivered to the turbine combustor for mixing with the compressed ambient gas flow to form a combustible mixture. The combustible mixture is burned and forms a recirculated gas flow that drives the turbine. The recirculated gas flow is recirculated using the recirculation loop. The turbine is operated at a target operating speed and then reaches substantially stoichiometric combustion. At least a portion of the recirculated gas flow is extracted using an extraction conduit that is fluidly connected to the turbine compressor.

International Classification:

F02C 6/00

US Classification:

60 3952, 60772, 60785, 60 39182, 60792, 60 3915

Abstract:

At least one main air compressor makes a compressed ambient gas flow. The compressed ambient gas flow is delivered to both master and slave turbine combustors at a pressure that is greater than or substantially equal to an output pressure delivered to each turbine combustor from each turbine compressor as at least a first portion of a recirculated gas flow. A fuel stream is delivered to each turbine combustor, and combustible mixtures are formed and burned, forming the recirculated gas flows. A master and slave turbine power are produced, and each is substantially equal to at least a power required to rotate each turbine compressor. At least a portion of the recirculated gas flow is recirculated through recirculation loops. At least a second portion of the recirculated gas flow bypasses the combustors or an excess portion of each recirculated gas flow is vented or both.
