What is a High temperature and low dust SCR denitrification? Introduction to the Working Principle of SCR denitration

High temperature and low dust SCR denitrificationdelective catalytic reduction technology is an efficient flue gas denitrification technology.，at the start of the operation,Under the action of catalyst, reducing agents (such as ammonia, urea, etc.) react with nitrogen oxides in flue gas to convert them into harmless nitrogen and water vapor.，It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the High temperature and low dust SCR denitrification technology can significantly reduce the concentration of nitrogen oxides (NOx) in flue gas and make it meet strict environmental protection emission standards. This high-efficiency denitration ability is mainly due to the promotion of the catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.、Technology has been developed and applied for many years, and it is mature and stable. The High temperature and low dust SCR denitrification has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the High temperature and low dust SCR denitrification technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.、The technology is suitable for many industries and processes, such as coal-fired power plants, iron and steel smelting, cement production and so on. These industries will produce a large number of NOx emissions in the production process, and the High temperature and low dust SCR denitrification technology can provide effective denitrification solutions for them. In addition, the gate technology can be adjusted and optimized according to different flue gas components and emission requirements to meet different denitration requirements.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency.

Under the action of catalyst, the reducing agent selectively reacts with nitrogen oxides (NOx) in flue gas to generate pollution-free nitrogen and water vapor. Because NH3 is selective, it only reacts with NOx and basically does not react with O2, so this technology is called selective catalytic reduction denitrification.，is designed by One-combustion energy saving with advanced technology。
