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.
