Oxy-fuel combustion on circulating fluidized bed (CFB)

Abstract: Oxy-fuel fluidized bed combustion can burn fuels in an energy-efficient manner, while offering a pure stream of CO 2 suitable for sequestration. Pilot-scale test units demonstrate all of the well-established advantages of air-blown circulating fluidized bed combustion (CFBC) technology in terms of low emissions and fuel flexibility when operating with pure oxygen. Research is still required to study the sulphation process and determine the potential for fouling due to carbonation if the unit is operated above 900 °C. Currently, efforts to commercialize this technology are making rapid strides and it is anticipated that there will be full-scale demonstrations within the next several years.
