Nowadays, trust friends are short-term, long-term and often concerned about the quality of the atmosphere. In recent years, the "haze" has made many families with children and probably people suffering from related diseases headache. But I don't know if my friends ask whether one of the causes of haze is nitrogen oxide, and how is nitrogen oxide caused? Nitrogen oxide is caused by high temperature, and the higher the temperature, the more easily it will cause more nitrogen oxide. However, it is widely used in our daily life, and it is also the steam pot where there are many nitrogen oxides. In order to manage the environment, the low nitrogen incinerator was selected.
The low nitrogen incinerator usually accepts methods such as exhaust gas or flue gas recycling (EGR or FGR), chemical growth agent (such as ammonia), catalyst help, etc. to reach the goal of low nitrogen oxide generation, because the flame temperature is short and long, often tense variables. The higher the flame temperature, the higher the NOx concentration. The preheating of the atmosphere and the temperature of the furnace are related to the temperature of the flame, so as to have a huge impact on the occurrence of NOx. When too much atmosphere increases across stoichiometry, the amount of NOx produced increases first. Because the inhibition incineration temperature has a huge impact first, when too much atmosphere continues to grow, the amount of NOx produced will first fall. Because of the reality and economy, it is impossible or impossible to reduce NOx through the application of too much atmosphere. The only way to reduce NOx is to accept exhaust gas or flue gas recycling (EGR or FGR), chemical growth agent (such as ammonia), catalyst and other methods. Plans for applications such as low NOx baffles and atmosphere classification and flue gas re cycling. Flue gas recycling can be accomplished by introducing the incineration product into the flame from the furnace or by using the mixture of exhaust system and atmosphere or fuel to lower the flame temperature. The oxygen that controls the feedback speed is also diluted, thus reducing the probability that the available oxygen will come in to generate NOx feedback.
