Soot blower - Wikipedia

A sootblower is a device for removing the soot that is deposited on the internal furnace tubes of a boiler during combustion to prevent plugging of the gas passes and maintain boiler efficiency.. Types of soot blowers: Wall Blowers also known as IRs (Insertable Rotating) Long Retractable Soot Blower (LRSB) or IK (Insertable Kinetic) Air Heater Blower.
