Operation control method of pulverized coal mill and pulverized coal mill.

摘要

PROBLEM TO BE SOLVED: To provide an operation control method of a powdered coal mill, which can rapidly cope with the change in loading.;SOLUTION: When the feeding amount of coal is minimum, the number of table rotations is set to be minimum. When the feeding amount of coal is maximum, the number of table rotations is set to be maximum. From the minimum number of table rotations to the maximum number of table rotation, the number of rotations for crushing is controlled according to a function F for controlling the table rotation number, increasing gradually the number of rotations corresponding the increase in the feeding amount of coal.;COPYRIGHT: (C)2012,JPO&INPIT
