The invention relates to the technical field of
hearth combustion, in particular to a low-
NOX and low-CO
gas burner special for a low-temperature
hearth, which comprises a
barrel, a pretreatment placement
assembly is mounted at the bottom end of the
barrel, the pretreatment placement
assembly comprises a base fixedly mounted at the bottom end of the
barrel, an upper fire pan
brick is mounted at the upper end of the barrel, and a lower fire pan
brick is mounted at the lower end of the barrel. A furnace bottom lining is arranged at the upper end of the barrel body, the upper fire pan
brick corresponds to the furnace bottom lining, a top plate is arranged at the upper end of the barrel body, a center air gun is vertically installed in the middle of the top plate, an air adjusting
butterfly valve is connected to the outer surface of the barrel body, and a fixing disc is arranged at the bottom end of the barrel body. An incandescent light gas
pipe is installed on one side of the fixing disc in a penetrating mode, a gas inlet
assembly is fixedly connected to the bottom end of the center gas gun, the generation amount of
NOX in
flue gas is reduced, meanwhile, a high-temperature area is formed by a
necking structure of the upper
brazier brick, the CO concentration in the
flue gas can be obviously reduced, and the overall
treatment effect of the
combustor is guaranteed.
