Gas burner

Abstract

The invention discloses a gas burner. The gas burner comprises a body frame and a plurality of burning fire grates. The multiple burning fire grates are arranged at the upper end of the body frame at intervals and in the same column. The upper end surface of each burning fire grate is provided with a plurality of flaming arrays. The multiple flaming arrays are arranged to be in at least one line in the length direction of the corresponding burning fire grate. Each flaming array comprises two first nozzles and at least one second nozzle. The first nozzles can generate horizontal flame towards all around. The second nozzles can generate longitudinal flame upwards. The two first nozzles of each flaming array are arranged oppositely. The length direction of each first nozzle corresponds to the length direction of the corresponding burning fire grate. The second nozzles are arranged between the two corresponding first nozzles. The lower end of the body frame is provided with an air inlet adjusting plate which is used for controlling air ventilation. The gas burner is higher in burning efficiency and has the characteristics of being higher in energy use efficiency and lower in cost.

Description

technical field [0001] The invention relates to the technical field of gas combustion, in particular to a gas burner. Background technique [0002] At present, the gas burners used in water heaters on the market basically adopt atmospheric combustion fire rows arranged in strips, and use the principle of mixed combustion with air to speed up the combustion speed. The flame hole is large, although it can spray a large amount of gas, but due to structural design defects, a large amount of gas or a mixture of gas and air is ejected quickly but it is difficult to fully burn, resulting in low flame temperature, so each gas burner generally burns Using 10-20 combustion fire rows not only wastes energy, but also is not conducive to cost control. In addition, insufficient combustion of gas will also produce many harmful gases, which is not conducive to people's health. Contents of the invention [0003] Based on this, the object of the present invention is to overcome the defects...

In addition, insufficient combustion of gas will also produce a lot of harmful gases, which is not conducive to people's health
