[0002] A burner is a device used in boilers, etc. The existing burner structure generally includes a fan and a gas pipe, a burner head, an ignition assembly (ignition electrode and flame detector, ignition controller), etc. The fan, gas pipe and burner head are connected by pipelines, etc. When working, the air output by the fan and the gas output by the gas pipe are mixed at the burner head, and then the ignition electrode of the ignition assembly ignites the gas, and the flame generated by the burner head acts on the boiler, etc., to achieve the purpose of heating the boiler, etc.

[0003] According to a Chinese patent with publication number CN218237460U, a low-nitrogen burner is disclosed. The utility model transmits wind to the connecting cylinder through a fan, and the wind passes through an outer sleeve and a flame stabilizing disk. Gas for combustion is stored in the gas source. The gas reaches the gas bin and the inner sleeve respectively through a gas transmission pipe. A part of the gas is discharged from the inner sleeve through the gas outlet at the top of the inner sleeve, and the other part of the gas is ejected through the injection pipe connected to the gas bin. The method of spraying gas at multiple positions is adopted, so that air and gas can be better combined, so that the gas burns more fully.
