Denitrification of steel plant heating furnace

Denitrification of steel plant heating furnaceAmmonia 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.，widely used incoal-fired power station,building materials,coal-fired power station,Gas power plant,cement plant and other industries。
