Abstract
In a soot blower, a heat transfer tube of a heat exchanger is arranged inside a pressure vessel, and gas for cleaning is injected toward the heat transfer tube from an injection pipe movable into and out of the pressure vessel. The soot blower includes a cylindrical casing provided to surround an insertion hole on the pressure vessel side into which the injection pipe is inserted, to extend outside the pressure vessel, the injection pipe being inserted into an inside of the casing; a support part provided inside the casing to guide movement of the injection pipe and to ensure airtightness between the casing and the injection pipe; and a gas supplying device provided immediately close to the support part to generate a jet stream of gas in a portion of the injection pipe that projects to the pressure vessel side.
