The present invention provides methods and system for power generation using a high efficiency combustor in combination with a CO2 circulating fluid. The methods and systems advantageously can make use of a low pressure ratio power turbine and an economizer heat exchanger in specific embodiments. Additional low grade heat from an external source can be used to provide part of an amount of heat needed for heating the recycle CO2 circulating fluid. Fuel derived CO2 can be captured and delivered at pipeline pressure. Other impurities can be captured.
1. A method of power generation comprising: introducing a fuel, O2, and a CO2 circulating fluid into a combustor, the CO2 being introduced at a pressure of at least about 12 MPa and a temperature of at least about 400° C.;combusting the fuel to provide a combustion product stream comprising CO2, the combustion product stream having a temperature of at least about 800° C.;expanding the combustion product stream across a turbine to generate power, the turbine having an inlet for receiving the combustion product stream and an outlet for release of a turbine...
