On the basis of fouling monitoring for heating surface of boiler NO.1 in Qingdao Power Plant

the variation of fouling rate for the said heating surface has been observed through varying the steam pressure used for sootblowers. The effectiveness of sootblowing under different steam pressure is compared

and the most reasonable sootblowing pressure being determined

providing reference for establishing reasonable and perfect optimal sootblowing model

which not only can effectively cleaning the ash deposite on the heating surface

but also can save the steam consumption for sootblowing

and can reduce abrassion of pipes on heating surface resulting from sootblowing.
