Embodiment Construction

[0007]FIG. 1 shows a cardboard tube 1, which accommodates a spark plug 2. The tube is provided at one end with a closure means, and a gas filling connection 5 is provided at the other end.

[0008]FIG. 2 shows an assembled embodiment 6 of the device.

[0009]Depending on the desired use, the tube can be made of any length. For example, in the embodiment depicted in FIG. 2, the tube is of a relatively small diameter (e.g., 3 cm to 15 cm), so that the tube may be introduced into a heat exchanger line containing gases within a combustion chamber.

[0010]After triggering of a blasting action that may destroy the entire cardboard tube, certain parts, such as a spark plug, threaded rod, closure means, and so forth, can be further used again.

[0011]FIG. 3 shows an alternative embodiment, wherein a first tube, which is connected to a second tube via a hinge 7, is fitted into a combustion chamber. Due to the hinge 7, the angle of the second tube (blasting tube) can be precisely adjusted according to ...

Abstract

A device for cleaning contamination in heat exchangers, waste-heat boilers, or combustion chambers is provided. In some embodiments, the device comprises a tube, a blasting body, and a combustible gas mixture within the tube. In some embodiments, the tube is destroyed after blasting. In some embodiments, the device further comprises a second tube comprising a blasting cord that is connected to a fuse, wherein the second tube is coupled to the first tube by a hinge.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of U.S. patent application Ser. No. 11 / 142,565, filed Jun. 1, 2005, pending, the disclosure of which is hereby incorporated herein by this reference in its entirety.BACKGROUND[0002]It is generally known that heat exchangers, waste-heat boilers, and combustion chambers (i.e., spaces in which combustion takes place which are provided with lines through which flows a medium to be heated) have to be cleaned at certain time intervals. The reason such cleaning becomes necessary is that the lines through which flows a medium to be heated gather soot on their outsides due to the combustion process within the combustion chamber, or else become covered by a layer of combustion residues that impede or prevent the transfer of heat. The gathering of soot and / or combustion residues ultimately reduces the level of efficiency of the heat exchanger, waste heat boiler, or combustion chamber.[0003]“Explosion cleaning proced...
