soot blowing for large coal fired boilers

Traditional Soot Blowers- steam soot blowers, air soot

A common application at oil, coal, or multi-fuel source power plants is retractable or rotary steam soot blowers. Several steam soot blowers are usually found at each level of the boiler tower. A traveling lance with nozzle jets penetrates narrow openings in the boiler tube banks to blast the tubes clean.

Soot Blower Erosion - We Prevent Boiler Slagging & Spray

The boiler soot blowing equipment uses high-efficiency venturi nozzles and superheated steam as a cleaning medium to maximize blowing coverage and remove porous soot deposits or buildup. A spray pressure control unit included in the poppet valve guarantees constant pressure and provides convenient adjustment of nozzle pressure.
