In today's life, the use of glass is very extensive, so the glass kiln has become an indispensable core equipment, the nitrogen oxides produced by it will also seriously pollute the environment, the adoption of SCR denitrification equipment can greatly reduce the emission of exhaust gas, to achieve sustainable development.

In daily life, the use of glass is very extensive, it almost permeates all aspects of our lives, glass because of its transparent, beautiful, good chemical stability, easy to process and other characteristics, plays an important role in modern society, with the progress of science and technology, the application field of glass is still developing. Glass melting furnace is the core equipment of glass manufacturing industry, in the glass production process, need to use glass melting furnace to produce, its main role is to melt glass raw materials (quartz sand, sodium carbonate, limestone, etc.) at high temperature to form a uniform glass liquid, this process is crucial for glass production.

In the production process of glass furnaces, nitrogen oxides (NOx) will be produced. SCR (selective catalytic reduction) denitrification equipment is usually installed in the exhaust gas control link of the flue gas treatment of glass furnaces. Under the action of catalysts, ammonia or urea is used to reduce NOx into harmless nitrogen and water.

SCR denitrification equipment is usually installed after electric dust removal to reduce the impact of dust on the catalyst. SCR denitrification technology has the advantages of high denitrification efficiency, mature technology and reliable operation, and has been widely used in glass flue gas denitrification treatment. The design and application of SCR denitration mainly need to consider the outlet temperature, the inlet temperature into the denitration, and the air volume to ensure the efficient and stable denitration equipment. When the denitrification efficiency can reach more than 90%, it is necessary to optimize the flow field distribution of the reactor, the uniformity of ammonia injection, and the volume margin of the catalyst to ensure stable efficiency and control ammonia escape. We can ensure that the ammonia escape data is less than 3ppm while achieving ultra-low emission in the field of nitrogen oxide emission, which has a strong comprehensive competitiveness. SCR denitrification equipment plays a crucial role in the exhaust gas control of glass furnace flue gas treatment, helping to reduce NOx emissions and meet environmental requirements.
