Abstract (en)
[origin: WO8600391A1] A method and a tool for increasing the width in the clear of a chimney, for instance for the cleaning of chimneys, combustion chambers, boilers and the like, which on internal surfaces are covered with coatings, e. g. tarry deposits, by means of strokes from chains. The tool is provided with a holder (4) located at the end of a rotatable shaft (6), to which holder are attached chains parts (5), e.g. consisting of simple, elongated chain links, so embodied that the chains (5) are located in several levels at right angles to the axis of rotation and are firmly fixed. In this manner several impacts at one single point are obtained, the chains being kept in their tracks by the neighbouring chains, thereby obtaining a much more effective and rapid chimney cleaning, just asto a large extent soot flakes are pulverized, whereupon they drop to the bottom in the chimney. The method and the tool may also be used for increasing the width in the clear in comparison with the original width in the clear, whereupon a chimney lining may be inserted.
