As shown in fig. 5 and 6, in the embodiment shown in fig. 5 and 6, considering that the temperature of the upper portion of the burner head 10 is higher than the temperature of the lower portion when the burner burns, the cooling requirement of the upper portion of the burner head 10 is stronger than that of the lower portion of the burner head 10. To achieve this, the windows 58 are designed in the present embodiment to have an inverted trapezoid shape, so that the windows 58 taper from top to bottom, which allows the upper portion of the windows 58 to draw in more air to cool the upper portion of the outer wall 54 of the burner head, which has a higher temperature. The inverted trapezoid shape shown here is only an example and other tapered shapes may be used. Other structures of the burner in this embodiment are the same as those of the above embodiment, and will not be described here again.
During operation, the fuel gas is injected from the nozzle 14 to cause the air flow channel 28 and the lower part of the nozzle 14 to form a certain vacuum degree, and due to the negative pressure, normal-temperature air outside the combustion head 10 is sucked into the cooling flow channel 44 through the window 58, and the air passes through the heat dissipation rib plate 60 and the cooling flow channel 44 to take away heat transferred from the inner wall of the combustion head 10 through heat convection so as to cool the combustion head 10 and improve the working environment of the combustion head 10.
The self-cooling injection burner of the present application retains the advantages of the injection burner and also increases the cooling function for the burner head 10. The heat dissipation rib plates 60 are arranged to strengthen heat transfer, and the air participating in combustion supporting firstly participates in cooling the combustion head 10 and then participates in combustion. The enthalpy value of the mixed gas in the mixing pipe 12 is improved, so that the combustion stability is improved, the service life of the combustion head 10 is prolonged, and the radiation of the combustion head 10 to the environment is reduced.
