Abstract (en)
[origin: EP0343434A1] The device serves for removing residues deposited on an inner wall (7) of a pipe carrying hot gases and/or vapours. This device has a scraping device, which can be activated by means of an axially extended shaft (13), and at least one discharge orifice (16) for the removed residues. <??>The intention is to provide a device, from which residues can be removed using simple means from regions subject to temperatures of over 1300 DEG C. This is achieved in that the scraping device has at least one metal part (15) wound in a helical shape in the axial direction and connected to the shaft (13). In this arrangement the shaft (13) is of axially displaceable design. The shaft (13) is driven in such a way that the metal part (15) can be screwed into the pipe in a corkscrew-like manner.
