<p>The disclosure relates to an apparatus for cleaning an opening (1) in the wall (2) of a soda recovery boiler (3), and an outlet spout (4), the apparatus comprising a carrier (5) for a cleaning device (6) and drive means (7). The carrier (5) and the drive means (7) fulfil the function of operating device for the cleaning device (6). The cleaning device (6) is, on cleaning movements, movable in and out through the opening (1) and up and down along the outlet spout (4). The operating device realises the cleaning movements and displays a rotary unit (10) for rotation of a tool included in the cleaning device (6) about a longitudinal axis (12) in the carrier (5). The cleaning device (6) is double-sided and eccentric in relation to the longitudinal axis (12). The disclosure further relates to a method of cleaning an opening (1) in the wall of a soda recovery boiler (3) and an outlet spout (4), comprising the steps that an elongate cleaning device (6) is directed in towards the opening (1), that the cleaning device (6) is moved towards and through the opening (1), as well as along the spout (4) and back to a position of rest, that the cleaning device (6) is rotated about a longitudinal axis (12) to the cleaning device (6) and that the cleaning device (6) is moved towards and through the opening (1) as well as along the spout (4) and back to a position of rest. The cleaning is carried out at different radial distances from the longitudinal axis (12) depending upon the rotary position of a cleaning tool (11) disposed on the cleaning device (6).</p> |
