What is the difference between low nitrogen combustion engine and ordinary combustion engine?

　　1. Different emissions:

　　Because of the difference of combustion methods and furnace layout, the original NOx emission of the laminar combustion, chamber combustion and circulating fluidized bed boiler is also quite different. Generally speaking, when the low nitrogen incineration technology in the furnace is not specially accepted, the original NOx emission of the circulating fluidized bed boiler is low, and the original NOx emission of the laminar combustion boiler represented by the chain boiler is slightly low. The boiler of the pulverized coal industry is the chamber combustion boiler, and the higher the original NOx emission is, The emission of famous low nitrogen steam boilers in China is very low.

　　2. Technical differences of steam boiler:

　　In view of the difference in credible incineration methods of laminar combustion, chamber combustion and CFB boiler, different low nitrogen incineration technologies are accepted. For laminar combustion boiler, air distribution is often used to accept atmosphere classification and flue gas recycling to complete low nitrogen incineration. Under the influence of flue gas recycling on the typical section incineration of laminar combustion boiler, the technology of connecting atmosphere classification experiences semi coke catalytic recovery of NOx. The super recovery denitrification technology in furnace is In recent years, the newly developed denitration technology in the furnace has experienced ammonia injection in a reasonable position in the combustion flame area, and completed the denitration simply in the high-temperature flame. It is important to optimize and mediate the position of secondary air outlet, coal feed port and diffuse flow of low nitrogen steam boiler, or to increase flue gas reincarnation system.

　　3. Safety difference:

　　In the middle, after a large number of experiments on the low nitrogen incineration technology in the furnace of laminar combustion, chamber combustion and circulating fluidized bed boiler, it has been verified in engineering application. As a whole, the safety of low nitrogen boiler is a little higher, so its sales volume is more and more high than in the past year. There are numerous users because of its high safety and small threat to space situation, which is also the same with general steam One of the great differences in pot tension.

　　The innovative product of low nitrogen steam boiler technology is the basic place for manufacturing energy-saving and environmental protection products. The low nitrogen steam boiler technology has gained great effect through numerous experiments and engineering applications. The low nitrogen steam boiler has been widely used in many homes, not only protecting the situation, saving energy, but also mastering pollution. This technology is also worth our continuous holding Research and develop applications.
