FLUIDIZED BED TYPE REACTION FOR THE COMBUSTION OF PULVERIZED COAL

摘要

pof the Invention A centrifugal spreader type feeder supplies a mixture of particulate limestone and coal to the top of a fluidized bed reactor having a flow of air upward therethrough. Large particles of particulate matter are distributed over the upper surface of the bed to utilize the natural mixing within the bed, while fine particles are directed into a turbulent downflow region established within the bed./p[CA1137825A]
