In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
As shown in fig. 1, the burner 100 provided by the present invention includes a burner body 110, a burner head 120 and a fire cover, wherein the burner head 120 is disposed at an air inlet end of the burner body 110 and is communicated with a gas pipeline (not shown in the figure), the burner head 120 is further provided with an air inlet 121, and the air inlet 121 allows air to flow into the burner body 110 and to be mixed with gas in the burner body 110. The fire lid sets up the end of giving vent to anger of combustor main part 110, the fire is covered and is provided with the fire hole, and the mist of gas and air passes through the fire lid is given vent to anger and is burnt, preferably, the fire lid includes interior fire lid 130 and outer fire lid 140, interior fire lid 130 and outer fire lid 140 are the loop configuration, interior fire lid 130 sets up outer fire lid 140's radial inboard.
As shown in fig. 2 and 3, the inner fire cover 130 and the outer fire cover 140 are annular shell structures, each annular shell structure comprises a top wall and two side walls which are oppositely arranged and connected with the top wall, and the fire holes are formed in the side walls and/or the top wall of the annular shell structure. Specifically, the inner fire cover 130 is provided with a first fire hole 131, the outer fire cover 140 is provided with a second fire hole 141, in this embodiment, the first fire hole 131 is formed on the radially outer side wall and the radially inner side wall of the inner fire cover 130, the second fire hole 141 is formed on the radially outer side wall of the outer fire cover 140, and preferably, the first fire hole 131 and the second fire hole 141 may each include one or more holes with different sizes. Be provided with annular groove-shaped gas outlet on the combustor main part 110, the gas outlet is provided with two, two the gas outlet respectively with interior fire lid 130 corresponds with outer fire lid 140, interior fire lid 130 and outer fire lid 140 cover are established on the gas outlet, and will the gas outlet seals, and the gas passes through interior fire lid 130 with the fire hole outflow on the outer fire lid 140 to burning in fire hole department.
As shown in fig. 3, in the present embodiment, the outer fire cover 140 is provided with a second fire hole 141, and a secondary air supplement channel is provided on a side wall forming the second fire hole 141, preferably, the secondary air supplement channel includes an air supplement groove 142 provided on a side wall of the outer fire cover 140, the air supplement groove 142 is formed by being recessed inward on an end surface of the side wall of the outer fire cover 140, which is not connected to a top wall thereof, and the air supplement groove 142 divides the second fire hole 141 into two parts located on two groove walls of the air supplement groove 142, and the two parts of the second fire hole 141 are communicated through the air supplement groove 142. Outer fire lid 140 with after combustor main part 110 assembly is accomplished the opening and the air intercommunication in tonifying qi groove 142, the air can enter into promptly in tonifying qi groove 142, it is right the gas that second fire hole 141 flows carries out the secondary tonifying qi, increases the oxygen content of second fire hole 141 department makes the gas burning more abundant to provide more heat energy. Moreover, since the air supply groove 142 is formed in the outer fire cover 140, the temperature of the outer fire cover 140 is high (about 300 ℃ higher than the ambient temperature) due to the combustion of the gas, and when the air enters the air supply groove 142, the air is in contact with the outer fire cover 140 and is heated by the high-temperature outer fire cover 140, and the heated air is mixed with the gas flowing out of the second fire hole 141 to supply oxygen for the combustion of the gas. The preheated air is mixed with the fuel gas, so that the heat absorption of the cold air to the flame can be reduced, and the temperature of the flame can be increased, particularly, the temperature of the flame can be increased by about 50 ℃. In addition, in an operating state, the opening of the air supplement groove 142 is located at the lower end of the outer fire cover 140, and the opening is downward, air enters the air supplement groove 140 from the lower end of the outer fire cover 140 and absorbs heat at the lower part of the outer fire cover 140, while the flame on the outer fire cover 140 is at the upper part of the outer fire cover 140, and the preheating of the air by the outer fire cover 140 does not affect the temperature of the flame.
