This Pratt and Whitney Rocketdyne project will evaluate a novel process for pressurized oxy-combustion in a fluidized bed reactor. The pressurized combustion in oxygen and the recycle of carbon dioxide gas eliminates the presence of nitrogen and other constituents of air, minimizing the generation of pollutants and enabling the economic capture of CO2 gas.
This project focuses on development of an oxygen-fired pressurized fluidized-bed combustor (Oxy-PFBC). The Oxy-PFBC operates at high pressure and improved efficiency, lowering capital and operating cost, and incorporates limestone injection to facilitate SO2 removal, reducing emission control equipment costs. Specifically, this project will design, build, and test a small-pilot scale Oxy-PFBC combustor to provide data necessary for scale-up.
