One method of operation of the retractable soot blower is on automatic control of flue gas temperature. There is a disadvantage to this in that during soot blowing, a temperature reduction occurs because the steam used for soot blowing cools the tubes and therefore the blowing could cause quite a drop in steam production at an inconvenient time.
This result is indicated by higher flue gas temperature, lower boiler output, additional tube erosion and leakage, unplanned shutdown for soot cleaning. Boiler soot cleaning methods . Over the past decades, power industry is fighting against soot buildup with boiler soot cleaning technology.
