Introduction to Denitrification of flue gas from steel plants, SCR denitration specifications, model parameters

Denitrification of flue gas from steel plantsdelective catalytic reduction technology is an efficient flue gas denitrification technology.，is a common Denitrification of flue gas from steel plants，the principle is simple.Ammonia gas or other suitable reducing agent (such as urea aqueous solution) is sprayed into the flue gas upstream of the catalyst at high temperature. 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.，can be customized according to user's needs.。

1、Brief introduction of Denitrification of flue gas from steel plants

Denitrification of flue gas from steel plantsit 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.，is a kind of Denitrification of flue gas from steel plants manufactured by One-combustion energy saving。
