It is generally known that heat exchangers, waste-heat boilers and combustion chambers, that is to say spaces in which combustion takes place and which are provided with corresponding lines through which flows a medium to be heated, have to be cleaned at certain time intervals. The reason for that cleaning operation is that the lines through which the medium to be heated flows soot up at their outside due to the combustion process within the combustion chamber or are covered by a layer of combustion residues which impede or prevent the transfer of heat, which ultimately reduces the level of efficiency of the installation. It is here that the invention is involved, the object thereof being to avoid the previous disadvantages and in addition also to permit a cleaning process if the temperature within the space to be cleaned has not yet fallen to room temperature or a temperature below 100.degree.C. A device for cleaning contamination in heat exchangers, waste-heat boilers or combustion chambers, characterised in that the device comprises a tube which is of a great length with at the same time relatively small diameter, wherein a combustible gas mixture and/or a blasting body is provided within the tube and the tube is destroyed after blasting and that the tube comprises a first tube and a second tube hingedly connected thereto and arranged within the second tube is a fuse which is connected to a blasting cord.
