Device for incinerating waste gas

Abstract

A device for incinerating waste gases has a combustion chamber, burner for burning waste gas in the combustion chamber, and a tubular conduit extending substantially vertically from the combustion chamber so that products of combustion of the waste gas in the combustion chamber travel vertically upwardly through the tubular conduit, the tubular conduit being composed of a plurality of tubular elements located one above the other and arranged relative to one another so as to form a gap between each two neighboring tubular elements for introducing air into an interior of the tubular conduit through the gaps.

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims:  
     
         1 . A device for incinerating waste gas, comprising a combustion chamber; means for burning waste gas in said combustion chamber; and a tubular conduit extending substantially vertically from said combustion chamber so that products of combustion of the waste gas in said combustion chamber travel vertically upwardly into said tubular conduit, said tubular conduit being composed of a plurality of tubular elements located one above the other and arranged relative to one another so as to form a gap between each two neighboring tubular elements for introducing air into the interior of said tubular conduit through said gaps.  
     
     
         2 . A device as defined in  claim 1 , wherein said tubular elements have different diameters such that a tubular element with a greater diameter is located above a tubular element with a smaller diameter to form said gap therebetween.  
     
     
         3 . A device as defined in  claim 1 , wherein said tubular elements have a cross section other than circular.  
     
     
         4 . A device as defined  1 , wherein said tubular elements of said tubular conduits are formed so that said gaps are open outside so that the air is aspirated through said gaps from outside inwardly into each of said tubular elements.  
     
     
         5 . A device as defined in  claim 1 , wherein the number, size and position of said gaps are chosen so that the wall temperature of the tubular elements does not exceed a specified value.  
     
     
         6 . A device as defined in  claim 1 , wherein the number, size and position of said gaps are chosen so as to provide the maximize possible dilution of the combustion products before said products exit said tubular conduit.  
     
     
         7 . A device as defined in  claim 1 , wherein the number, size and position of said gaps are chosen so as to ensure the combustion products exceed a specified temperature for a specified duration before said products exit said tubular conduit.  
     
     
         8 . A device as defined in  claim 1;  and further comprising means for forced supply of air through said gaps between said tubular elements.  
     
     
         9 . A device as defined in  claim 1 , wherein an additional tubular enclosure is arranged around said tubular conduit so that air is supplied first in a space between said tubular element and said tubular enclosure and then travels through said gaps into an interior of said tubular conduit.  
     
     
         10 . A device as defined in  claim 1 , wherein each of said gaps is subdivided in a circumferential direction by a plurality of partitions which form a plurality of slots and also serve for connecting said tubular elements with one another.  
     
     
         11 . A device as defined in  claim 1 , wherein the partitions of one gap are circumferentially offset relative to the partitions of the other gap.
