5、Working principle of Step furnace flue gas denitrification

Step furnace flue gas denitrificationAmmonia 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.，the main features are Good selectivity, Mature technology, Stable operation, Environmental protection and pollution-free and High denitration efficiency，it has been widely used in Gas power plant, cement plant, coal-fired power station, building materials, Gas power plant and other industries，support customization。
