| description | The invention discloses a fuel staged injection type low-nitrogen burner. The fuel staged injection type low-nitrogen burner comprises a gas chamber, an ignition assembly, a first fuel gas assembly and a second fuel gas assembly. The gas chamber is provided with an inner cavity, and a combustion-supporting gas inlet and a gas outlet are formed in the surface of the gas chamber. The outer surface of the air chamber is provided with a concave area, and at least part of the air outlet holes are distributed in the concave area. The ignition assembly penetrates through the air chamber, and the ignition end of the ignition assembly is located in the center of the inwards-concave area. The first fuel gas assembly is used for supplying fuel gas to the inner cavity and the inwards-concave area at the same time. The ignition assembly comprises a Laval nozzle, an ignition air gun, an igniter and a flame detector. The large-diameter end of the Laval nozzle is located in the inner cavity, and the small-diameter end of the |
