FLUIDISED BED REACTOR

摘要

A coal feed system for a fluidized bed reactor in which a grate 20 is supported in a housing 14 and adapted to receive a bed 18 of particular material at least a portion of which is combustible. Air is passed through the grate and the particulate material to fluidize the particulate material. A relatively coarse particulate fuel material is distributed to the upper surface of the bed and a slurry containing a relatively fine particulate fuel material is distributed into the bed below the upper surface of the bed. The coal feed is separated in separator 30 having a grid 34 allowing finer particles in the form of a slurry to be fed via reservoir 50 into the bed.
