Developments in circulating fluidised bed combustion

is applied to a CFBC boiler, the combustion temperature can be controlled by recycling a portion of the cooled solids to the furnace through a fluidised-bed heat exchanger, therefore minimal flue gas recirculation is required. This characteristic allows the oxy-CFB boiler to be made smaller and less expensive in a new unit application.
