  • Compressor flow extraction apparatus and methods for supercritical COoxy-combustion power generation system
    Patent number: 10787963
    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.

  • Power generation system using closed or semi-closed Brayton cycle recuperator
    Patent number: 10598093
    Abstract: A power generation system includes a turbine having an outlet. A high temperature recuperator has an inlet and is connected to the turbine outlet. A low temperature recuperator is connected to the high temperature recuperator. Each of the high and low temperature recuperators include a plurality of matrix panels interconnected together that define hot fluid channels and cold fluid channels arranged adjacent to each other in a counterflow and stair-step configuration. A compressor is connected to the low temperature recuperator and turbine.
