What is a Catalyst based denitrification system? Introduction to the Working Principle of SCR denitration system

Catalyst based 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.，Simple structure and advanced technology.，generally, it is composed of Catalyst supply system, Temperature control and monitoring system, Catalyst reactor, Flue gas mixing and distribution system, control system and other major components，widely used in iron and steel plant, coal-fired power station, metallurgy, cement plant, Gas power plant and other fields，be loved by our customers.。
