Abstract (en)

The explosive cleaning system uses a first fixed tube (Rohr-1) with a water inlet (Wassereinlass) and an air inlet (Lufteinlass). The mixture of water and air flows through this tube, and passes through a flexible link (Gelenk) to a second movable tube (Rohr-2). It flows into the space between the boiler tubes (8,9) to be cleaned. A wire (Zundleitung) passes through the first tube and the link to an igniter (Zunder) and an explosive cord (Sprengschnur) in the second tube. The tubes may be made of cardboard or copper and burst with the water and air scattered by explosion of elongated cord.
