circulating fluidized bed boiler fuel particle size

Technology Overview Circulating Fluidized-bed Combustion

The CFB operates at higher fluidization velocity lower mean bed particle size and higher recirculation rate than conventional FBC systems. Probable advantages of CFBC over the traditional FBC process include: more flexibility in fuel selection reduced number of fuel feed points higher combustion efficiency better calcium utilization and ...

Jun 15 2003 · Previous studies [4] [11] [12] [24] show that fresh feed particles usually have an initial period of rapid attrition before the attrition rate slows down to a steady level. Ray et al. [4] carried out particle attrition experiments in a fluidized bed using limestone particles with a size range 3001000 m.

Circulating fluidized bed - Wikipedia

Fluidization is the phenomenon by which solid particles are transported into a fluid like state through suspension in a gas or liquid. In fact there is a simple and precise way to classify the various fluid-particle beds (Winaya et al. 2003; Souza-Santos 2004; Basu 2006). Most of the CFB operating and environmental characteristics are the direct results of the hydrodynamicbehaviour. Numerous researchers have studied the hydrodynamics of CFB (Yang 1998; Basu 2006; Rhode
