Directing against the comparatively serious problems of slagging and ash deposition in 2×600 MW boilers burning Shenhua coal in Guodian Dingzhou Power Plant

test on pollution behavior of heating surfaces in boiler no.1 has been carried out.Through model for monitoring pollution on the heating surface

the pollution growing behavior

as well as upper and lower limitation of pollution on each heating surface have been monitored

and the blowing effectiveness of sootblowers being checked.The test data can provide basis for optimizing the sootblowing mode and for ensuring safe and economic operation of the boiler.
