Chapter 1 Coal Generation and Circular Fluid - CFBC Boiler

High combustion temperatures in coal-fired boilers can cause slag and fouling problems in the furnace, superheater and heater sections depending on the quality of the coal . Therefore, regular soot blowing is necessary to keep these areas clean. On the other hand, the combustion temperature in the CFBC boilers is low, around 900 ° C., which reduces the problems of slag or fouling.

investment cost. The first commercial fluidized bed boilers utilizing a solids separator for solids recirculation was constructed in the 1970's by Lurgi (Reh et al. 1979). The idea of a circulating fluidized bed (CFB) boiler is to use a relatively high fluidization velocity (up to 6 m/s) and then to
