CFB boiler, which also serves for maintaining inert bed inventory in furnace. The in situ sulphur capture using lime stone in CFB boilers are represented by the reactions 1 & 2: (Balance Sulphur capture by limestone CaCO 3→ aO+O 2 (1) CaO + SO 2 + ½ O 2→ aSO 4
Boiler Control for Fossil-Fired Utility Boilers 3 The Air Controls provide the ability to maintain a uniform response for either one or two fan operation. In addition, bias action applied to the fans will not result in a process upset. The FD fans are not released to automatic unless at least one ID fan has been placed in automatic.
The circulating fluidized bed (CFB) use high fluid velocity to provide better gas-solid contact by providing more intense mixing of the fluid so that better quality of product can be obtained. However, the high gas velocities and the recirculation of solids may make the CFB system much more expensive in term of power requirement and investment
