Title:
固体燃料粉砕装置及びこれを備えた発電プラント並びに固体燃料粉砕方法
Document Type and Number:
Japanese Patent JP7341669
Kind Code:
B2
Abstract:
Disclosed is a solid fuel crushing device capable of stably supplying pulverized fuel to a boiler even when biomass fuel is used. The solid fuel crushing device comprises: a rotary table; a crushing roller crushing biomass fuel, which is a solid fuel, between rotary tables; a rotary classifier having a plurality of blades installed along a circumferential direction centered on a rotation axis and classifying the biomass fuel after being pulverized by a crushing roller; a blower part supplying primary air from the rotary table side toward the rotary classifier; and a control part controlling the primary air supply amount (A) supplied from the blower part. The control part controls the primary air supply amount (A1) approximately constant over an operating range of a boiler to which the biomass fuel after classification is supplied from the rotary classifier.
