Abstract

A body to be installed into a radiant tube for reduction of pollutants, the body including a body having a tube shape including a length, an outer diameter and an inner diameter, the body further comprises a proximal surface, a terminal surface, and a circumferential surface extending between the proximal surface and terminal surface, and the body is configured to be disposed at an axial distance from a terminal end of a burner, wherein the axial distance (AD) is at least a 0.1% of the length of the body.

What is claimed is: 
     
         1 . A body configured to be installed into a radiant tube for reduction of pollutants, the body comprising:
 a body having a tube shape including a length, an outer diameter, and an inner diameter, wherein the body further comprises a proximal surface, a terminal surface, and a circumferential surface extending between the proximal surface and terminal surface; and   wherein the body is configured to be disposed at an axial distance from a terminal end of a burner, wherein the axial distance (AD) is at least a 0.1% of the length of the body.   
     
     
         2 . The body of  claim 1 , wherein the axial distance is within a range of at least 0.1% and not greater than 1000% of the length of the body or any percentage therebetween. 
     
     
         3 . The body of  claim 1 , wherein the axial distance is within a range of at least 0.1% and not greater than 100% of a wall thickness of the body or any percentage therebetween, wherein the wall thickness is the difference in the outer diameter of the body relative to the inner diameter. 
     
     
         4 . The body of  claim 1 , wherein the body consists of a single monolithic body having a single axial opening extending the length of the body and a solid side wall surrounding the axial opening for the length of the body. 
     
     
         5 . A system configured to be installed into a radiant tube for reduction of pollutants, the system comprising:
 a body having a tube shape including a length, a width, an outer diameter, and an inner diameter, wherein the body further comprises a proximal surface, a terminal surface, and a circumferential surface extending between the proximal surface and terminal surface; and   a positioning device configured to engage the body, wherein the positioning device is configured to adjust an axial distance between the body and a combustion source.   
     
     
         6 . The system of  claim 5 , wherein the positioning device comprises a first positioning element and a second positioning element, wherein the first positioning element comprises a terminal end including an engagement structure configured to engage the body, and wherein the second positioning element comprises a terminal end including an engagement structure configured to engage the body. 
     
     
         7 . The system of  claim 5 , wherein the positioning device comprises a proximal end and a terminal end and a first cross bar between the proximal end and the terminal end configured to engage the body. 
     
     
         8 . The system of  claim 7 , wherein the body comprises a notch configured to engage the first cross bar of the positioning device. 
     
     
         9 . The system of  claim 7 , wherein the terminal end of the positioning device terminates outside of the radiant tube. 
     
     
         10 . The system of  claim 9  wherein the terminal end of the positioning device is accessible to an outside user. 
     
     
         11 . The system of  claim 5 , wherein the positioning device is configured to adjust the body between a first position and a second position along an axial length of the radiant tube. 
     
     
         12 . The system of  claim 11 , wherein the first position is at least 0.01 cm and not greater than 100 cm from the combustion source. 
     
     
         13 . The system of  claim 11 , wherein the second position is at least 0.02 cm and not greater than 100 cm from the combustion source. 
     
     
         14 . The system of  claim 11 , wherein the first position and the second position are spaced at least 0.01 cm and not greater than 100 cm away from one another. 
     
     
         15 . The system of  claim 5 , wherein at least one portion of the positioning device is configured to be accessible by a user at a safe distance from the combustion source. 
     
     
         16 . The system of  claim 11 , wherein at least one portion of the positioning device is configured to be adapted between a first position and a second position without changing a state of the combustion source. 
     
     
         17 . A method for reducing pollutants of a combustion assembly comprising:
 measuring pollutants from a combustion reaction within a combustion assembly including at least one combustion source contained within a radiant tube; and   changing a position of a body within the radiant tube relative to the combustion source while the combustion source is combusting; wherein the body comprises a length, an outer diameter, and an inner diameter, wherein the body further comprises a proximal surface, a terminal surface, and a circumferential surface extending between the proximal surface and terminal surface.   
     
     
         18 . The method of  claim 17 , wherein changing a position of the body comprises adjusting the position without interrupting the combustion source. 
     
     
         19 . The method of  claim 17 , wherein changing a position of the body comprises adjusting the body between a first position and a second position along an axial length of the radiant tube. 
     
     
         20 . The method of  claim 17 , wherein changing a position of the body comprises using a positioning device.
