POWER PLANT AND METHOD OF OPERATION

摘要

A power plant arrangement and method of operation is provided. The power plant arrangement includes at least one main air compressor and at least one gas turbine assembly. Each assembly includes a turbine combustor for mixing a portion of compressed ambient gas with a portion of a recirculated low oxygen content gas flow and a fuel stream for burning to form the recirculated low oxygen content gas flow. A recirculation loop for recirculating at least a portion of the recirculated low oxygen content gas flow from the turbine to a turbine compressor is provided. At least one auxiliary apparatus is fluidly connected to the main air compressor and may be at least partially powered by the compressed ambient gas flow.
