### Optimization of particle size distribution in circulating

· Among the factors affecting the performance of the CFB boiler the particle size distribution (PSD) of coal gangue feed was found to be the most significant. This has been reflected by that only a slight variation in the average diameter of coal feed can impact the stability of both the crush system and CFB system significantly 9 10 .

· The size distribution produced by the ball milling of various crystalline and non-crystalline materials showed that initially there was a fairly even distribution over the size range up to 355μm. However as milling proceeded two distribution modes developed one at about 90μm (the persistent mode) and one at about 250μm (the transitory mode).

CiteSeerXDocument Details (Isaac Councill Lee Giles Pradeep Teregowda) The development of coal-water slurries as a boiler fuel is rapidly approaching commercialization. As distinguished from dilute pipeline slurries fuel slurries are stable highly-loaded (e.g. 70 dry coal by weight) liquids which can be transported stored pumped and burned like residual fuel oil.
