ABSTRACT:
A retractable sootblower for avoiding and dislodging accumulated soot and ash. The sootblower includes an elongate housing and a blowing tube or blowing tube assembly reciprocable in the housing. The blowing tube is extended and retracted by pressurized gas. Pressurized gas is also applied to the sootblower. An internal gas channeling arrangement couples the pressurized gas to the blowing tube when the blowing tube is extended. The pressurized gas is thus discharged from the blowing tube when the blowing tube is extended. Additional structure is provided for rotating the blowing tube as it moves from the retracted position to the extended position.
