Directing against the problems existing in the coal pulverizing system of boiler no. 1 in Guangzhou Power Plant

such as coarse particles of the pulverized coal

low uniformity

large resistance in the separator

serious wornout

and insufficient output etc.

retrofit of coarse pulverized coal sepa-rater has been carried out. After retrofitting

the output of coal pulvevizing system has been enhanced

its specific consumption lowered

combustibles in fly ash of the boiler obviously decreased

wornout of heating surface of the boiler alleviated

safety in operation of the entire boiler unit increased
