Burner on duty is connected with gas inlet pipe on duty and air intlet on duty by combustion gas on duty, air Mixture conduit, and gas inlet pipe on duty is installed in a side in chamber, the end;

Be located at the burner port that encircles in the burner on the ring wall and can arranging 3 rows with the ring wall vertical direction, level angle from top to bottom is respectively 20 °, 25 ° and 5 °, and hole and circle center line connecting angle are respectively: 15 °, 15 ° and 0 °.

One side also is equipped with main gas inlet pipe in chamber, the end, and its upper end laterally is provided with several main combustion gas squit holes, and main combustion gas squit hole places in main combustion gas, the air hybrid chamber.

Set burner port and baseplane angle a be between 0～30 ° on the ring wall that encircles in main burner, and circle center line connecting angle b is between 0～30 °.

Be provided with combustion gas on duty, air Mixture guide hole at the center of flow spoiler, be provided with the impeller of some radiation oblique arrangement, between impeller, formed air cavity in its periphery.

Good effect is: 1, owing to be provided with horizontal main combustion gas squit hole on main air inlet pipe, help fully mixing of combustion gas and air; 2, because air intlet on duty is located at the bottom of gas inlet pipe on duty and is placed in the chamber, the end, help entering and mixing of fresh air; 3,, can make the further dispersion and mixing of combustion gas and Air mixing gas owing in main combustion gas, air hybrid chamber, flow spoiler is installed; 4, owing in main burner shell and main burner, be provided with main combustion gas, air preheat hybrid chamber between the ring, help the preheating of combustion gas, air mixer and fully burning; 5, be provided with burner shroud on duty because burner on duty is located in the main burner in the middle of the ring and in its outside, can guarantee that its burning is not subjected to the interference of flow perturbation, be difficult for flame-outly, guarantee its security, and be arranged on the outside and compare long service life and prevent scaling loss; 6, because the burner port setting has angle, the rotation that can realize flame is with overlapping, thereby reduces flame height, improves flame temperature and also prevents ring in the scaling loss burner, raising service life.So the utlity model has and be subjected to that external interference is little, flame height is low, temperature is high, sufficient combustion, heat utilization efficiency height, energy-conservation, safe characteristics.Suitable various Gas appliance burnings obtain heat and use.
