Abstract
A power generation system burns a fuel in a gas in a combustion chamber, producing one or more combustion products and heating a working fluid, preferably supercritical CO2, that is chemically the same as a combustion product. The working fluid is mixed with the combustion products to form a combustion output mixture which is used in a turbine to drive a shaft of the turbine connected with a generator, producing electricity. The turbine outputs an exhaust that goes to a working fluid recycling system that connects the turbine outlet with the combustion chamber. The fluid recycling system has a radial compressor that receives and pressurizes the exhaust mixture and sends it to a chamber that has a bleed outlet and a recycling outlet. The recycling outlet transmits a recycled portion of the exhaust mixture to the combustion chamber, and the bleed outlet carries an excess portion of the exhaust mixture that is not to be recycled to an extraction system that removes it from the power generation system for use in other applications.
