Technical Field

The utility model relates to the technical field of burners, in particular to an improved upper air inlet burner.

Background

At present, most of the existing household gas burners are atmospheric burners, also called partially premixed burners. The working principle is as follows: the gas flows out from the nozzle at a certain flow rate under a certain pressure, enters the injection pipe, and attracts a certain amount of surrounding air under the injection action of the energy of the gas, wherein the air is called primary air. The primary air and the fuel gas are mixed in the injection pipe and the mixing cavity of the burner and then flow out through the fire holes to be combusted. Air is drawn from the surrounding of the flame to support combustion during the combustion process, and the air is called secondary air.
