Ultra low nox insulating burner without collar

Abstract

A burner comprising is provided including a burner tube formed at least partially from a first material having a plurality of openings. The plurality of openings are sized to allow a fluid but not particles of debris contained within the fluid to flow there through. A flange extends outwardly from a portion of the burner tube and is receivable within an embossment formed in an adjacent component. The flange is formed from a second material having a plurality of openings such that heat transfer between the flange and the adjacent component is limited.

1 . A burner comprising:
 a burner tube formed at least partially from a first material having a plurality of openings, the plurality of openings being sized to allow a fluid, but not particles of debris contained within the fluid to flow there through; and   a flange extending outwardly from a portion of the burner tube and being receivable within an embossment formed in an adjacent component, wherein the flange is formed from a second material having a plurality of openings such that heat transfer between the flange and the adjacent component is limited.   
     
     
         2 . The burner according to  claim 1 , wherein the flange is positioned at an outlet end of the burner tube. 
     
     
         3 . The burner according to  claim 1 , wherein the first material having a plurality of openings and the second material having a plurality of openings are substantially identical. 
     
     
         4 . The burner according to  claim 3 , wherein the flange is integrally formed with a portion of the burner tube. 
     
     
         5 . The burner according to  claim 1 , wherein the first material having a plurality of openings and the second material having a plurality of openings are different. 
     
     
         6 . The burner according to  claim 5 , wherein the flange is removably or fixedly coupled to a portion of the burner tube. 
     
     
         7 . The burner according to  claim 1 , wherein when the flange is received within the embossment, the flange does not extend beyond a plane defined by the a surface of the adjacent component. 
     
     
         8 . A burner assembly, comprising
 a plurality of burners, each burner including a burner tube defining a burner axis, the burner tubes having an inlet, an outlet, and a flange extending outwardly from a portion of the burner tube; and   a partition plate arranged generally perpendicular to a horizontal plane containing the plurality of burner axes, the partition plate including a plurality of partition openings complementary to and arranged coaxially with the plurality of burners, wherein the flange of each burner is configured to mount to the partition plate, the flange being configured to limit heat transfer between the burner and the partition plate.   
     
     
         9 . The burner assembly according to  claim 8 , further comprising a lock plate mounted positioned adjacent a surface of the partition plate, the lock plate being configured to engage a portion of at least one of the plurality of flanges to restrict movement of a burner away from the partition plate. 
     
     
         10 . The burner assembly according to  claim 8 , wherein the partition plate includes a plurality of embossments, each of the plurality of flanges being receivable within one of the plurality of embossments. 
     
     
         11 . The burner assembly according to  claim 10 , wherein a thickness of the flanges is less than a depth of the embossments. 
     
     
         12 . The burner assembly according to  claim 8 , wherein the flange is arranged at an outlet end of each of the plurality of burner tubes. 
     
     
         13 . The burner assembly according to  claim 8 , wherein the burner tube is formed from a first material having a plurality of openings, the plurality of openings being sized to allow a fluid, but not particles of debris contained within the fluid to flow there through. 
     
     
         14 . The burner according to  claim 13 , wherein the flange is formed from a second material having a plurality of openings. 
     
     
         15 . The burner according to  claim 14 , wherein the first material having a plurality of openings and the second material having a plurality of openings are substantially identical. 
     
     
         16 . The burner according to  claim 15 , wherein the flange is integrally formed with a portion of the burner tube. 
     
     
         17 . The burner according to  claim 14 , wherein the first material having a plurality of openings and the second material having a plurality of openings are different. 
     
     
         18 . The burner according to  claim 5 , wherein the flange is removably or fixedly coupled to a portion of the burner tube.
