FLUIDIZED MATERIAL PARTICLE DIAMETER CONTROL DEVICE FOR CIRCULATING FLUIDIZED BED TYPE FURNACE

摘要

PURPOSE: To perform a stable combustion and a stable operation in a circulating fluidized bed type boiler and the like by a method wherein a particle diameter of fluidized material in a furnace is controlled to a specified value. ;CONSTITUTION: A part of fluidized bed material collected by a cyclone 2 and returned back to a combustion device 1 is taken and cooled by a cooling device 14, thereafter the particle diameter is detected by a classifying machine 17. Then, a motor 19 for a crusher 8 is controlled on the basis of the detected value.;COPYRIGHT: (C)1996,JPO
