With the acceleration of industrialization, coal, as an important energy source, will produce a large amount of nitrogen oxides (NOx) in the power generation process, which has a serious impact on the environment and human health.
Coal, as a traditional fossil energy, has always been an important source of power production. As one of the most widely used energy sources in the world, the emission of nitrogen oxides generated in the power generation process has attracted increasing attention. Nitrogen oxides not only cause pollution to the atmosphere, but also pose a threat to human health. It is of great significance to treat the exhaust gas of coal mine gas generator by denitrification.
In the combustion process of coal mine gas generator, the high temperature conditions will lead to the reaction of nitrogen and oxygen to become NOx, NOx mainly contains nitric oxide (NO) and nitrogen dioxide (NO₂), the concentration in the tail gas directly affects the degree of atmospheric pollution and human health.
In the face of the challenge of global warming, the coal industry has contributed to the national goal of “double carbon emission reduction” by improving energy efficiency and promoting clean technologies to reduce greenhouse gas emissions. Under normal circumstances, we use flue gas denitrification technology, in the combustion process, the tail gas is treated after the end to remove NOx, the main technology includes selective catalytic reduction (SCR). SCR denitrification technology is one of the most widely used flue gas denitrification technologies at present. Under a certain temperature and catalysis, NOx can be reduced to nitrogen and water. SCR denitrification technology has the advantages of high denitrification efficiency and stable operation.
Although denitrification technology has made some progress, it still faces some challenges, such as high cost, by-product treatment, catalyst durability, etc. Green Valley Environmental Protection will continue to conduct technology research and development to improve denitrification efficiency, reduce costs, improve its activity and selectivity under low temperature conditions, optimize system integration and process flow. The use of intelligent and automated technology to improve the stability and reliability of denitration system, reduce labor costs and operational errors and other problems. Future denitration technology discoveries will focus more on cost-effectiveness, environmental friendliness and technological innovation.
