bed temperature for CFB boilers

Circulating fluidized bed - Wikipedia

2019-8-14 · Another type of CFB is circulating fluidized bed gasification (CFBG), which is preferable to other type of gasifiers. CFBG has a high mass and heat transfer rate as well as high efficient gas-solid contacting. At low operating temperature of CFBG, a longer residence time of solid can be achieved leading to a higher gasification yield.

Fluidized Bed Boiler - an overview ScienceDirect Topics

The bed temperature is greatly influenced by fuel composition. For high-sulfur fuel, e.g., pet-coke, the bed temperature has to be maintained at around 1123 K for optimum sulfur capture. While low-sulfur low reactivity fuel, like anthracite culms, can be safely operated at a higher temperature to ensure high combustion efficiency.
