摘要： Ambient air is compressed into a compressed ambient gas flow with a main air compressor (12). The compressed ambient gas flow is delivered to a turbine combustor (32) and mixed with a fuel stream (28) and a portion of a recirculated low oxygen content gas flow (50) and is burned to form the recirculated low oxygen content gas flow (50) and drive a turbine (34). A portion of the recirculated low oxygen content gas flow (50) is recirculated from the turbine (34) to the turbine compressor (30). The compressed ambient gas flow rate and the fuel stream flow rate are adjusted to achieve substantially stoichiometric combustion. An excess portion, if any, of the compressed ambient gas flow is vented. A portion of the recirculated low oxygen content gas flow (50) is extracted using an extraction conduit (48).

摘要： Ambient air is compressed into a compressed ambient gas flow (26) and delivered to a turbine combustor (32). An exhaust port is opened. A turbine shaft (22) is rotated at an ignition speed and a fuel stream (28) is delivered to the turbine combustor (32) for mixing with the compressed ambient gas flow (26) to form a combustible mixture. The combustible mixture is burned and forms a recirculated gas flow (50) that drives the turbine (34). The recirculated gas flow (50) is recirculated using a recirculation loop (52). The turbine (34) is operated at a target speed and then reaches substantially stoichiometric combustion. At least a portion of the recirculated gas flow (50) is extracted using an extraction conduit (48) that is fluidly connected to the turbine compressor (30).

摘要： At least one main air compressor (12) makes a compressed ambient gas flow (26).

A fuel stream (28) is delivered to the turbine combustor (32), and a combustible mixture is formed and burned, forming the recirculated gas flow (50). A turbine power is produced that is substantially equal to at least a power required to rotate the turbine compressor (30). At least a portion of the recirculated gas flow (50) is recirculated through a recirculation loop (52). An excess portion of the recirculated gas flow (50) is vented or a portion of the turbine compressor exhaust (44) bypasses the turbine combustor (32) or both.
