4、Low temperature SCR method for denitrification principle

Low temperature SCR method for denitrificationat runtime,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.，usually used in iron and steel plant, coal-fired power station, building materials, Gas power plant, metallurgy and other fields，the full name is selective catalytic reduction technology, which is an advanced flue gas denitrification technology.。
