2、Introduction of advantages of Low temperature catalytic flue gas denitrification equipment

The advantages of Low temperature catalytic flue gas denitrification equipment are as follows:

1. High efficiency denitration capacity

Gate is famous for its high efficiency of denitration, which can usually reach more than 90% denitration efficiency. This means that the Low temperature catalytic flue gas denitrification equipment technology can significantly reduce the concentration of nitrogen oxides (NOx) in flue gas and make it meet strict environmental protection emission standards. This high-efficiency denitration ability mainly benefits from the promotion of catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.

3、Low temperature catalytic flue gas denitrification equipment introduction video

Speak directly with facts on the spot。

Low temperature catalytic flue gas denitrification equipment

As you can see from the live video.，One-combustion energy saving 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.。

5、Low temperature catalytic flue gas denitrification equipment principle

Low temperature catalytic flue gas denitrification equipmentin the course of work,Catalysts are used to promote the selective catalytic reduction reaction between reducing agents (such as ammonia and urea) and NOx in flue gas. Under the action of catalyst, the reductant preferentially reacts with NOx to generate harmless nitrogen and water vapor, but hardly reacts with oxygen in flue gas. This chemical reaction is usually carried out in the temperature range of 200-450℃, and the specific reaction temperature depends on the type of catalyst selected.。
