Energy-saving burner of low-pressure long-range industrial kiln

The invention belongs to the technical field of industrial kilns, and particularly relates to an energy-saving burner of a low-pressure long-range industrial kiln. The energy-saving burner of the low-pressure long-range industrial kiln comprises an end cover, a shell, a small fuel gas pipe, a middle combustion-supporting pipe, an outer combustion-supporting air sleeve, air blades, an electrode anda premixing layer, a fuel gas inlet is formed in the top end of the end cover, the shell is installed on one side of the end cover, a combustion-supporting air inlet is formed in the top end of the shell, and the bottom end of the fuel gas inlet is connected with the small fuel gas pipe. The energy-saving burner of the low-pressure long-range industrial kiln saves energy, the range of the spray gun is long, and the problems of fracture surface temperature difference and carbon deposition and dirt falling are solved by increasing combustion-supporting air; combustion-supporting air is small inair pressure and sufficie
