Some troublesome problems of boiler No.8 in Baotou Thermal Power Plant No.1

such as somewhat higher flame temperature in the furnace

slagging on the water-wall tubes

frequent burn-out of the burners

and overtemperature of the superheater etc.

are existing from the beginning of putting into operation up to now

influencing seviously upon the safe

stable and ecomomic operation of the said power plant. Hence

a comprehensive remedical scheme

including technical retrofitting of burners

superheater

and steam soot-blower system

as well as adding on-line monitoring system for promary air and secondary air of the said boiler

has been put forward. After implementation of the said scheme

the results are comparatively remarkable

having basically solved the problems existing in the combustion facilities of the said boiler.
