At present, low-nitrogen boilers are the first choice for many users, because low-nitrogen boilers have incomparable advantages over ordinary boilers. Recently, a customer came to us, Dongfang Yongjie, and asked what is the difference between the low-nitrogen burner of the boiler and the ordinary boiler ? Our technicians gave an answer to this question.
1. Differences in emissions:
Due to the different combustion methods and furnace structures of laminar combustion, chamber combustion and circulating fluidized bed boilers, their original NOx emissions are also quite different. The original emission of NOx is low, and the original emission of NOx of the layer-fired furnace represented by the chain furnace is also slightly lower. The pulverized coal industrial boiler is a chamber-fired boiler. The higher the original emission of NOx, the emission of well-known low-nitrogen boilers in China is greatly reduced.

Our technicians gave an answer to this question.
2. Boiler technology is different:
Layer-fired, chamber-fired, and circulating fluidized bed boilers can adopt different low-nitrogen combustion technologies according to different combustion methods. For the air distribution of layer-fired boilers, air classification and flue gas recirculation are often used to achieve low-nitrogen combustion ; Under the influence of recirculation on the combustion of the typical section of the layer-fired boiler, NOx is catalytically reduced by semi-coke combined with air classification technology; in-furnace super reduction and denitrification technology is an emerging in-furnace denitrification technology in recent years. Ammonia is sprayed to achieve direct denitrification in a high temperature flame. The low nitrogen boiler mainly optimizes and adjusts the position and distribution of the secondary air outlet and coal feed outlet, or adds a flue gas recirculation system.
3. Different security
After the center has conducted a large number of tests on the low-nitrogen combustion technology in the furnace of laminar combustion, chamber combustion and circulating fluidized bed boilers, it has been verified in engineering applications. Generally speaking, low-nitrogen boilers are safer. So in recent years, its sales are getting higher and higher, and many users buy it because of its high safety and small threat to the space environment, which is also one of the important differences between it and ordinary boilers.
Innovative products of low-nitrogen boiler technology are the basis for the production of energy-saving and environmentally friendly products. The low-nitrogen boiler technology has achieved great results after many tests and verifications in engineering applications. Low-nitrogen boilers are widely used in many industries. It is widely used, which not only protects the environment, saves energy, but also controls pollution. This technology is also particularly worthy of our continued research and development and application.
