METHOD AND APPARATUS OF PREHEATING A SOOTBLOWER LANCE |
摘要 |
A retractable sootblower is provided with means for preheating the sootblower lance prior to introduction of blowing medium into the lance to prevent condensation of the blowing medium which would be subsequently discharged from the lance against internal boiler surfaces accelerating surface erosion. The sootblower of the present invention preheats the lance by only providing blowing medium to the lance after at least a portion of the lance has been extended into the boiler and heated by hot boiler gases to thereby prevent condensation of the blowing medium within a cooled lance.
