Abstract

A block and burner assembly including a flat flame burner sub-assembly which includes a flat flame burner body in fluid communication with a gas source. The flat flame burner body includes a gas inlet in fluid communication with the gas source and a gas nozzle, and a fuel inlet in fluid communication a fuel nozzle, wherein the gas nozzle is arranged to at least partially encompass the fuel nozzle. The block and burner assembly includes a flat flame burner block arranged to receive at least a portion of the fuel nozzle and at least a portion of the gas nozzle, a staged injector sub-assembly in fluid communication with the gas source, and a staged injector block connected to the flat flame burner block and arranged to receive the at least a portion of the staged injector sub-assembly wherein the flat flame burner block and the staged injector block are separable.

         2 . The block and burner assembly of  claim 1 , wherein the staged injector block is connected to a top side or a bottom side of the flat flame burner block. 
     
     
         3 . The block and burner assembly of  claim 1 , further comprising a bracket arranged to secure the staged injector block to the flat flame burner block. 
     
     
         4 . The block and burner assembly of  claim 1 , wherein the gas nozzle is arranged to taper from a first width and a first height to a second width and a second height, wherein the first width is smaller than the second width and the first height is greater than the second height. 
     
     
         5 . The block and burner assembly of  claim 1 , wherein the fuel nozzle is arranged to taper from a third width and a third height to a fourth width and a fourth height, wherein the third width is smaller than the fourth width and the third height is greater than the fourth height. 
     
     
         6 . The block and burner assembly of  claim 1 , wherein the gas nozzle is arranged to project a first distance from the flat flame burner body in a first direction and the fuel nozzle is arranged to project a second distance from the flat flame burner body in the first direction, wherein the first distance is equal to the second distance or wherein the first distance is less than the second distance. 
     
     
         7 . The block and burner assembly of  claim 1 , wherein the staged injector block comprises a plurality of gas channels, wherein each of the plurality of gas channels extends from a first side of the staged injector block to a second side of the staged injector block, and wherein a first gas channel of the plurality of gas channels is arranged non-parallel to a second gas channel of the plurality of gas channels. 
     
     
         8 . The block and burner assembly of  claim 7 , wherein the first gas channel of the plurality of gas channels comprises a first aperture proximate the first side of the staged injector block and a second aperture proximate the second side of the staged injector block, and wherein the first aperture is arranged a first aperture distance from the flat flame burner block and the second aperture is arranged a second aperture distance from the flat flame burner block, and wherein the first aperture distance is greater than the second aperture distance. 
     
     
         9 . A staged injector block comprising:
 a first side, a second side, a bottom surface arranged between the first side and the second side, and a first gas channel arranged between the first side and the second side, wherein the first side is arranged to receive at least a portion of a staged injector sub-assembly and comprises a first aperture in fluid communication with the first gas channel, and the second side comprises a second aperture in fluid communication with the first gas channel, the first aperture arranged a first aperture distance from a flat flame burner block in contact with the bottom surface of the staged injector block and the second aperture arranged a second aperture distance from the flat flame burner block wherein the first aperture distance is greater than the second aperture distance.   
     
     
         10 . The staged injector block of  claim 9 , further comprising a recess, wherein the recess comprises the first aperture. 
     
     
         11 . The staged injector block of  claim 9 , further comprising a second gas channel arranged between the first side of the staged injector block and the second side of the staged injector block, and wherein the first side of the staged injector block comprises a third aperture in fluid communication with the second gas channel and arranged a third aperture distance from the flat flame burner block, and the second side comprises a fourth aperture in fluid communication with the second gas channel and arranged a fourth aperture distance from the flat flame burner block wherein the third aperture distance is less than the fourth aperture distance. 
     
     
         12 . The staged injector block of  claim 9 , further comprising a second gas channel arranged between the first side and the second side, and wherein the first gas channel is arranged non-parallel to the second gas channel. 
     
     
         13 . The staged injector block of  claim 12 , further comprising a third gas channel arranged between the first side of the staged injector block and the second side of the staged injector block, and wherein the third gas channel is arranged non-parallel to the first gas channel and the second gas channel.
