Abstract
A fastening apparatus for a cleaning device based on introducing high-amplitude pressure waves by means of a hollow-cylindrical nozzle (19) into a boiler to be cleaned through an opening in the boiler wall (20) has a cleaning device housing body (10) which is fastenable to the boiler wall (10) with the aid of a boiler-side fastening flange (30, 32), wherein the longitudinal direction of the hollow-cylindrical nozzle (19) is concentric with respect to the opening in the boiler wall (20) and is orthogonal to the boiler axis. A series of damping elements (50) are arranged at regular angular distances around the hollow-cylindrical nozzle (19) in the longitudinal direction thereof and are each fastened at one free end to the boiler-side fastening flange (30, 32) and at the other free end in each case to the housing body (10) such that, when said high-amplitude pressure wave is triggered in the cleaning device, the housing body (10) thereof is held back resiliently pointing away from the boiler in the longitudinal direction and can be brought back into the starting position.
Claims (13)
