Why choose a low nitrogen burner

　　Nowadays, it is believed that anybody is very concerned about air exceptional issues. In current years, the "haze" triggered by using air air pollution has made many households with youngsters or people with associated ailments have a headache.But I do not be aware of if you apprehend that one of the reasons of smog is nitrogen oxides, and how are nitrogen oxides formed?Nitrogen oxides form due to the fact of high temperatures, and the higher the temperature, the simpler it is to shape more nitrogen oxides.And in our every day lifestyles use the largest, the most extensive, is now the most nitrogen oxide production area is the boiler.And it is to manipulate this situation that the preference of low nitrogen burner has been made.yBNBoiler Burner

　　Low nitrogen burners commonly use exhaust fuel or flue fuel recirculation (EGR or FGR), chemical components (such as ammonia), catalyst AIDS, etc., to reduce the manufacturing of nitrogen oxides, because flame temperature is the most important variable.The higher the flame temperature, the greater the attention of NOx.Air preheating and furnace temperature are associated to the flame temperature and consequently have a widespread impact on the production of NOx.As the excess air increases past the stoichiometry, the amount of NOx produced starts to increase.As the suppression of combustion temperature begins to have a tremendous impact, the quantity of NOx produced will begin to decline as excess air continues to increase.Reducing NOx via the use of extra air is usually not possible or perfect for practical and monetary reasons, so only exhaust gas or flue gas recirculation (EGR or FGR), chemical additives (e.g. ammonia), catalyst AIDS, etc.Designs such as low NOx baffles and air classification and flue gas recirculation.Flue gas recirculation can be achieved by introducing combustion merchandise into the flame from the furnace or through the use of the exhaust machine to combine with air or gasoline to limit the flame temperature.The oxygen that controls the reaction fee is additionally diluted, lowering the probability that on hand oxygen will enter NOx to produce the reaction.yBNBoiler Burner
