Abstract

A fastening device for a cleaning device by introducing pressure waves through a hollow nozzle into a boiler to be cleaned through an opening in the boiler wall has a housing body, which can be fastened to the boiler wall with the aid of a fastening flange on the boiler side, the hollow nozzle being concentric with the opening in the boiler wall and orthogonal to the boiler axis. Damping units are arranged at regular angular intervals around the hollow nozzle in the longitudinal direction thereof and are each fastened with one free end to the boiler-side fastening flange and with the respective other free end to the housing body. When the pressure waves are triggered, the housing body is resiliently retained in the longitudinal direction away from the boiler and brought back into the initial position.

Abstract

A method for cleaning a pressure-resistant boiler region (10) with pressure pulses (21), which are produced by a cleaning device (20) and are introduced into the boiler (10) via an outlet opening (22) assigned to the cleaning device (20), wherein, using a control unit (30), a pressure pulse is emitted by the cleaning device (20) into the boiler region (10) at predetermined cleaning intervals to produce pressure pulses, is characterized in that a measured value characterizing the degree of soiling of the boiler is picked up by a sensor (40) and is compared with a predetermined first threshold value, wherein, depending on the correlation of the measured value with the degree of soiling, the cleaning interval is set to a shorter cleaning interval and/or the cleaning energy is set to a higher cleaning energy if the measured value is above or below the first threshold value.

Abstract

An apparatus and method for producing explosions, including a pressure-resistance container having a main explosion chamber introduced therein, further including a supply line for supplying a flowable explosible material, and a drain opening for the directed drainage of gas pressure caused by the ignition of the explosible material. The drain opening is closed directly by a closure means, preferably a plunger, which is pressed against the drain opening using a gas spring and held closed substantially up to the time of ignition. Before the actual main explosion, the closure means is moved by the igniting and the pressure force of an auxiliary explosion, thereby exposing the drain opening.
