Introduction to SCR Low Temperature Denitrification System and SCR denitration structure principle

SCR Low Temperature Denitrification Systemit refers to the process of removing nitrogen oxides from flue gas to reduce environmental pollution. NOx is a pollutant harmful to the atmospheric environment, which has strong irritation and toxicity, and will lead to environmental problems such as acid rain and photochemical smog, and also endanger human health. The main principle of flue gas denitrification technology is to reduce NOx to nitrogen and water by adding appropriate reducing agent or catalyst in the combustion process or flue gas treatment system, so as to reduce NOx emission.，Stable operation,Mature and stable technology,Promote sustainable development,Environmental protection and pollution-free,Less secondary pollution，is developed and improved by One-combustion energy saving。
