Developments in circulating fluidised bed combustion

The combustion temperature of a CFBC boiler is in the range between 800ºC and 900ºC, which is significantly lower than a pulverised coal fired boiler (1300 –1700ºC). The low combustion temperature results in a considerably reduced NOx formation in CFBC compared to pulverised coal combustion.

David A. Tillman, in Coal-Fired Electricity and Emissions Control, 2018. 2.1.3 Control of NO x. Fluidized bed boilers of all types are, by virtue of their combustion temperatures, low NO x generators. Operating the reactors at temperatures ≤1700°F virtually eliminates formation of any thermal NO x.All NO x is generated from the conversion of fuel nitrogen.
