Power plant and method of use

摘要

A power plant arrangement and method of operation are provided. The power plant arrangement comprises at least one main air compressor (12) and one or more gas turbine assemblies. Each assembly comprises a turbine combustor (32) for mixing a portion of a compressed ambient gas flow (26) with a portion of a recirculated low oxygen content gas flow (50) and a fuel stream (28), and burning the combustible mixture to form the recirculated low oxygen content flow (50). The assembly further comprises a turbine compressor (30), fluidly connected to the turbine combustor (32), and connected to a turbine shaft (22) that is arranged to be driven by rotation of a turbine (34). The assembly also comprises a recirculation loop (52) for recirculating at least a portion of the recirculated low oxygen content gas flow (50) from the turbine (34) to the turbine compressor (30).
