PURPOSE:To prevent excessively large energy loss from occurring and eliminate the damage of a heat accumulating body by a structure wherein the more outward soot blower injection nozzles locate the larger the diameter of the nozzles is set or the more inward said nozzles locate the smaller said diameter is set and the more outward the nozzles locate the shorter the distance between the nozzles and the heat accumulating body is set or the more inward said nozzles locate the longer said distance is set. CONSTITUTION:The longer the radii R1-R8, on each of which nozzles lie, from an axis 7 becomes, the larger the diameter of the nozzles among the nozzles 111-118 is set and at the same time the longer said radii R1-R8, on each of which nozzles lie, from the axis 7 becomes, the shorter the distance between the nozzle 11 and a heat accumulating body 5 is set, resulting in making the work-done of each nozzle 11 with respect to the unit surface area of the heat accumulating body 5 constant. As a blower 9, a tapered tube, the diameter of which increases gradually towards outward, is employed. Consequently, no waste of soot blower work-done due to the result that the work-done at inward portion is larger than that at outward portion occurs and furthermore no damage of the heat accumulating body develops.
