1、Brief introduction of Catalyst oxidation denitrification equipment

Catalyst oxidation denitrification equipmentdelective catalytic reduction technology is an efficient flue gas denitrification technology.，it is widely used in building materials, metallurgy, Gas power plant, iron and steel plant and cement plant，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.，it is widely used in coal-fired power station, building materials, coal-fired power station, cement plant, metallurgy and other industries，has been favored by more and more customers.。
