Oxy-fuel Circulating Fluidized Bed Combustion

Oxy-fuel CFBC requires significantly less recycled flue gas to control boiler temperature due to the re-circulating solids that effectively act as a heat moderator. This permits the use of a much higher oxygen concentration in the combustor, and allows the economics of oxy-fuel CFBC to be significantly improved over PC firing through a reduction of the size of the CFBC boiler island by as much
