[0012] Preferably, a plurality of nozzles are provided on the inner wall of the spray hole, and the nozzles are all connected to the air passage.

[0013] Through this solution, several nozzles all spray flames downward through the nozzle holes. Compared with a single nozzle, it is not only more reliable, but also can improve the combustion efficiency and help increase the temperature.

[0014] Preferably, an inner sleeve is provided in the spray hole, the inner sleeve is made of refractory metal, and the top inner wall of the inner sleeve is a curved reflector.

[0015] Through this solution, the inner sleeve can increase the service life of the device, and the reflector can reflect the heat in the furnace back to further improve the thermal insulation effect.

[0016] Preferably, a boss is provided on the inner wall of the heating hole, and the inner diameter of the boss is consistent with the inner diameter of the inner sleeve.
