A long retractable soot blower is used to remove ash in the boiler superheater and reheater area(also used for economizer). During soot blowing, the soot blower lance tube and nozzle head rotate and extend into the boiler flue to blow the ash on the heating surface, the effective blowing radius is around 2 ~ 2.5m. A long retractable soot blower can be used in the flue gas temperature up to 1300℃. After finishing soot blowing, the sootblower lance tube will retract back from the boiler to avoid being broken by high-temperature flue gas.
During the operation of the boiler, soot and coking on the heating surface are the most common phenomena, so it’s very necessary to install a soot blower at the power plant. At present, steam soot blowers and sonic soot blowers are the two main types of soot blowers installed in the power station boiler, steam soot blower is the most widely used and the most effective one.
