Patent ID: 8266913

Claim:
A power plant arrangement, comprising: at least one main air compressor for compressing ambient air into a compressed ambient gas flow; and two or more gas turbine assemblies fluidly connected by an inter-train conduit, each comprising: a turbine combustor, fluidly connected to the at least one main air compressor, for mixing at least a first portion of the compressed ambient gas flow with at least a first portion of a recirculated low oxygen content gas flow and a fuel stream to form a combustible mixture and for burning the combustible mixture and forming the recirculated low oxygen content gas flow; a turbine connected to the turbine combustor and to a turbine shaft, and being arranged to be driven by the recirculated low oxygen content gas flow from the turbine combustor; a turbine compressor, fluidly connected to the turbine combustor, and connected to the turbine shaft and being arranged to be driven thereby; and a recirculation loop for recirculating at least a portion of the recirculated low oxygen content gas flow from the turbine to the turbine compressor.
