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.

Pressurized fluidized bed combustion (PFBC) - ScienceDirect

Pressurized fluidized bed combustors are FBCs operated at elevated pressures. The high-temperature and high-pressure flue gas from the combustor can drive a gas turbine to obtain mechanical energy. Furthermore, heat can be recovered from the combustor as high-temperature and high-pressure steam to drive a steam turbine.
