Combustion method of low nitrogen burner gas fuel

Combustion method of gas fuel for low-nitrogen burner: In the process of using low-nitrogen burner, what are the types of flames of the burner? The effects of gaseous fuel and air flow on the flame length are as follows: Flame combustion: Flame combustion means that the light body charge and air are not pre-mixed before entering the combustion chamber, but are used to enter different combustion chambers. Combustion chamber, burning while mixing in the combustion chamber, the flame produced is longer. And there is a clear flame outline, also known as flaming combustion. When the use conditions are the same but the burner structure is different, the mixing situation and flame length are also different. More solid carbon particles are easily generated in the flame, and the flame blackness is larger. From the point of view of combustion, it seems that the generation of carbon particles is not ideal, but in fact most of these carbon particles can be burned out, and can greatly increase the radiation ability of the flame, thereby enhancing the heat transfer effect in the furnace, thus benefiting more than cons. Therefore, sometimes it is suspected that the luminous carbon particles are not enough, and then the gas is carbonized. The use of flame combustion can allow air and gas to be preheated to a higher temperature without being limited by the ignition temperature. The low-nitrogen burner is conducive to obtaining a higher combustion temperature with low calorific value gas and making full use of the waste heat surface of the exhaust gas to save fuel!
