The Necessity of Low Nitrogen Transformation of Gas Boiler


In recent years, the country has vigorously promoted the clean air plan, and natural gas has been used more and more as a clean energy source. However, the use of natural gas will cause certain nitrogen oxide pollution. In order to curb the emission of nitrogen oxides, Beijing had In July, a new gas-fired boiler emission standard was issued, stipulating that the nitrogen oxide emission of gas-fired boilers in use in the city should be lower than 80 mg/m3, and that of newly-built gas-fired boilers should be lower than 30 mg/m3. With the establishment of standards, boiler low-nitrogen transformation is also imminent.




Why does the boiler need low-nitrogen environmental protection transformation?




Optimizing the incomplete combustion problem




In order to ensure the complete combustion of fuel, it is usually necessary to supply a certain proportion of excess air in addition to the theoretical air volume required for combustion. On the premise of ensuring the thermal efficiency of combustion, a small excess air coefficient is used to reduce the oxygen concentration in the flue gas as much as possible. , will be able to effectively suppress the formation of NOx.




Reduce NOx emissions




When the boiler is operating at high load, the air volume of the blower is usually increased to increase the furnace temperature. At this time, the excess air coefficient is often large, the furnace temperature is high, and the amount of NOx generated is large. Boruite low-nitrogen boiler operates smoothly under high-load conditions, and at the same time controls the furnace temperature, which can effectively suppress the formation of NOx.




Control unreasonable furnace temperature




NOx nitrogen oxides are generated due to the oxidation of N2 in the combustion-supporting air at high temperature. Boruite’s low-nitrogen transformation can effectively control the combustion temperature below 1000 degrees, and supplemented by staged combustion, flue gas internal circulation and other technologies, so that NOx The concentration of nitrogen oxides is greatly reduced.




Steady burner effect




The key component of the gas boiler is the burner. The unstable burner has poor cycle effect, which is not conducive to controlling the flame temperature and easily causing the loss of boiler thermal efficiency. Boruite equips customers with original imported burners, which are reliable in quality and stable in operation, so that the combustion gas sucked into the furnace during the combustion process can participate in recirculation, reduce the oxygen concentration in the combustion area, reduce the flame temperature, and reduce nitrogen oxides Quantitative purpose.




What is the significance of gas boiler low nitrogen transformation?




1. It is conducive to improving the control effect of actual pollutants in the industrial field of our country and can make enterprises compete to establish a correct concept of environmental protection, and can also promote the development of environmental protection in our country.




2. Promoting the reform of my country's boiler industry has fundamentally established crisis awareness for my country's boiler merchants. Many merchants have also begun to improve the research and development level of low-nitrogen boilers, helping my country's boiler industry to achieve good changes, and allowing consumers to enjoy More high-quality and cheap products.
