Abstract: The present invention relates to a method for measuring the conditions inside a power boiler wherein a sootblower is used as a measuring probe. The invention also relates to a system for measuring the conditions in a power boiler, comprising a control unit, at least one sensor and a measuring probe placed inside said furnace, wherein said probe is arranged on a soot blower.

Abstract: This invention relates to a method of rebuilding a sootblowing system of a recovery furnace, said sootblowing system including a plurality of sootblowers (1), and each sootblower (1) including a frame (10), a moveable carriage (14) supported by the frame (10), a motor (2) for moving the carriage (14), a lance tube (11) mounted on the carriage (14) to be insertable into and retractable from the recovery furnace (8), said lance tube (11) having at least one nozzle (12), and a steam feed tube (45, 35, 15) connected to the lance tube (11) for feeding sootblowing steam to be ejected through said at least one nozzle (12) into the recovery furnace, said steam feed tube (45, 35, 15) having a first valve (3) arranged to admit steam through said at least one nozzle (12) only when the carriage with the lance tube (11) is in an activated position, i.e.
