Cleaning of a furnace

Abstract

The invention relates to a device (1) for cleaning a flue of a combustion system. Said device (1) comprises a nozzle head (8) that is located in a flue (2) during the cleaning process and directs a cleaning medium onto interior walls (9) of the flue (2) and/or against pipes which are arranged therein, a hose (5) that conducts the cleaning medium, is connected to the nozzle head (8), and can be introduced into the flue (2) such that the position of the nozzle head (8) in the flue can be adjusted, and a hose drum (4) for winding up or unwinding the hose (5). The inventive device (1) is characterized in that the hose drum (5) is mounted so as to be rotatable about a first axis (11) and a second axis. The angle of rotation of the nozzle head (8) in the flue (2) is varied by rotating the hose drum (4) about said two axes, and so is the vertical height of the nozzle head (8) if the hose (4) is introduced into the flue (2) from above.
