Oxy-fuel combustion consists of burning fossil fuels in a mixture of pure oxygen and re-circulated flue gas, resulting in CO2-rich flue gas (free of nitrogen, contrary to conventional air-fired power plants). The pure oxygen is supplied by a cryogenic air separation unit (ASU).
Reliable and robust process
Our systems have been proven and developed from existing technologies.
Adaptable to most boiler and fuel types with the potential for rapid scale up, even up to the 1,000 MWe range, and to existing power plants.

OXY-FUEL COMBUSTION CO2 CAPTURE
The oxy-combustion boiler is a carbon capture technology that has been under development for more than a decade, starting with research and the subsequent establishment of a laboratory pilot in the 1990s. GE has been at the forefront of oxy-fuel combustion development, and we:
developed the first oxy pilot plant at a site in Germany
demonstrated the entire oxy-technology chain including a gas processing unit in our boiler simulation facility located in Windsor, Connecticut, USA.
GE is also developing the gas processing unit (GPU), which is designed to further treat and process the flue gas downstream of the oxy-boiler, delivering CO2 at the required specification.
