Method of and apparatus for cleaning fouling in heat exchangers, waste-heat boilers and combustion chambers

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.

1 . A device for cleaning contamination in a heat exchanger apparatus, a heat boiler apparatus, or combustion chambers apparatus, by way of linear blasting, the device comprising:
 a first tube;   a hinge coupled to the first tube;   a second tube coupled to the first tube via the hinge;   a blasting cord disposed linearly in the second tube;   a fuse, which initiates blasting when triggered, disposed in the second tube and connected to the blasting cord; and   a fuse line disposed in the first tube and connected to the fuse; and wherein, in operation, the second tube shatters via linear blasting, providing particles thereof to strike and detach contamination in the heat exchanger apparatus, heat boiler apparatus, or combustion chamber apparatus.   
     
     
         2 . The device of  claim 1  further including a combustible gas mixture disposed in the second tube. 
     
     
         3 . A device for cleaning contamination in a heat exchanger, a heat boiler, or a combustion chamber, the device comprising:
 a tube;   a combustible gas disposed in the tube; and   a triggering spark plug disposed in the tube and exposed to the combustible gas; and   wherein, in operation, the tube shatters providing particles thereof to strike and detach contamination in the heat exchanger apparatus, heat boiler apparatus, or combustion chamber apparatus.   
     
     
         4 . The device of  claim 1  wherein the second tube consists essentially of metal material. 
     
     
         5 . The device of  claim 1  wherein the second tube is comprised of a material comprising a cardboard, a glass, a metal or a plastic. 
     
     
         6 . The device of  claim 3  wherein the tube is comprised of a material comprising a cardboard, a glass, a metal or a plastic. 
     
     
         7 . A method for cleaning contamination in a heat exchanger apparatus, heat boiler apparatus, or combustion chambers apparatus, using the device of  claim 3 , the method comprising
 terminating the operation of the heating assembly of the heat exchanger apparatus, heat boiler apparatus, or combustion chambers apparatus; and   triggering the device of  claim 3  when the temperature in the interior of the assembly is greater than 300° C., wherein, in response thereto, the tube shatters providing particles thereof to strike and detach contamination in the heat exchanger apparatus, heat boiler apparatus, or combustion chamber apparatus.   
     
     
         8 . The method of  claim 7  wherein triggering the device of  claim 3  when the temperature in the interior of the assembly is greater than 700° C., wherein, in response thereto, the second tube shatters providing particles thereof to strike and detach contamination in the heat exchanger apparatus, heat boiler apparatus, or combustion chamber apparatus. 
     
     
         9 . A device for cleaning contamination in a heat exchanger apparatus, heat boiler apparatus, or combustion chambers apparatus, the device comprising:
 a tube bundle comprising a plurality of coupled tubes, wherein each tube of the tube bundle comprises:
 a blasting tube; 
 a combustible gas disposed in the blasting tube; 
 a triggering spark plug disposed in the blasting tube and exposed to the combustible gas; and 
 wherein, in operation, the blasting tube shatters providing particles thereof to strike and detach contamination in the heat exchanger apparatus, heat boiler apparatus, or combustion chamber apparatus. 
   
     
     
         10 . The device of  claim 9  wherein the blasting tube of each tube of the plurality of tubes is comprised of a material consisting essentially of metal. 
     
     
         11 . A device for cleaning contamination in a heat exchanger apparatus, heat boiler apparatus, or combustion chambers apparatus, the device comprising:
 a tube bundle comprising a plurality of coupled tubes, wherein each tube of the tube bundle comprises:
 a first tube; 
 a second tube hingedly connected to the first tube; 
 a blasting body disposed in the second tube; 
 a fuse, to responsively initiate blasting, disposed in the second tube and coupled to the blasting body; 
 a fuse line connected to the fuse; and 
 wherein, in operation, the second tube shatters providing particles thereof to strike and detach contamination in the heat exchanger apparatus, heat boiler apparatus, or combustion chamber apparatus. 
   
     
     
         12 . The device of  claim 11  wherein the second tube of each tube of the plurality of tubes is comprised of a material consisting essentially of a metal.
