    摘要： A power plant and method of operation is provided. The power plant comprises at least one main air compressor (12), an oxidizer unit (62) configured to deliver a compressed oxygen-rich gas flow (24) to at least one gas turbine assembly. Each assembly comprises a turbine combustor (32) for mixing the compressed oxygen-rich gas flow (24) with a recirculated gas flow (50) and a fuel stream (28) to burn a combustible mixture and form the recirculated gas flow (50). A recirculation loop (52) recirculates the recirculated gas flow (50) from a turbine (34) to a turbine compressor (30). A recirculated gas flow extraction path (63) extracts a portion of the recirculated gas flow (50) and delivers this to a gas separation system (65). The gas separation system (65) separates the second portion of the recirculated gas flow (50) into a nitrogen portion and a carbon dioxide portion.

    摘要： In a power generating plant including a gas turbine (10) which utilizes fuel gas from an oxygen blown gasifier (26) for combustion at a predetermined pressure to drive a primary load, and where the fuel gas (40) is supplied from the gasifier at a pressure higher than the predetermined pressure, an arrangement isprovided to decrease the pressure of the fuel gas to a lower pressure required by the gas turbine. This arrangement includes a combustor (42) and an expander (48) downstream of the combustor, the combustor and the expander located between the gasifier and the gas turbine.
