As we all know, low nitrogen burner is mainly used in boilers, and low nitrogen boiler on the market has become the primary choice for many users. Do you know the difference between the boiler after low nitrogen burner and the ordinary boiler?
1. Differences in emissions:
Because of the different combustion modes and the different furnace structure, the original NOx emission of the layer combustion, the chamber combustion and the circulating fluidized bed boiler is different. Generally speaking, the original emission of the circulating fluidized bed NOx is low when the low nitrogen combustion technology is not specially used in the furnace, and the original emission of the NOx in the layer combustion furnace represented by the chain furnace is also slightly lower. Industrial boilers are chamber fired boilers, and the higher the NOx's original emissions, the less well-known domestic low nitrogen boilers are.
2. The technology of boiler is different:
Different low nitrogen combustion technology can be used in the layer combustion, room combustion and circulating fluidized bed boiler according to the different combustion modes. The low nitrogen combustion is realized by air classification and gas recirculation for the air distribution of the layer combustion boiler. Under the influence of the combustion of the typical section of the layer combustion boiler, the gas recirculation is combined with the air classification technology to pass the semi coke. Catalytic reduction of NOx, the technology of super reduction and denitrification in the furnace is a new technology for denitrification in the furnace in recent years. By spraying ammonia at a reasonable position in the burning flame area, the direct denitrification can be achieved in the high temperature flame. The low nitrogen boiler mainly adjusts and adjusts the location and distribution of the two outlets, coal outlets, or increases the flue gas recirculation system.
3. Different security
After a lot of experiments on low nitrogen combustion technology in the furnace of layer combustion, room combustion and circulating fluidized bed boiler, the center has been verified in engineering application. In general, the low nitrogen boiler has a higher safety. In recent years, its sales volume is higher and higher. There are many users because of its high safety and space ring. The threat of the environment is small and the purchase is also one of the important differences between it and ordinary boilers.
The technology innovation product of low nitrogen boiler is the root of the production of energy saving and environmental protection products. The low nitrogen boiler technology has made great achievements in many experiments and engineering applications. The low nitrogen boiler has been widely used in many industries, not only protecting the environment, saving energy, but also controlling the pollution. This technology is also worthy of our continued research and development.
