1、Brief introduction of Flue gas denitrification equipment for roasting furnace tail gas

Flue gas denitrification equipment for roasting furnace tail gasdelective catalytic reduction technology is an efficient flue gas denitrification technology.，in 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.，it is widely used in Gas power plant, cement plant, metallurgy, cement plant, iron and steel plant and other industries，the advantage is Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Flue gas denitrification equipment for roasting furnace tail gas can monitor the composition and emission concentration of flue gas in real time, and automatically adjust the injection amount of reductant and the active state of catalyst to ensure the stability and reliability of denitrification efficiency.、Intelligent control is gradually realized.

2、Flue gas denitrification equipment for roasting furnace tail gas video detail

One-combustion energy saving provides customers with on-site high-definition video, fully demonstrates the advantages of on-site Flue gas denitrification equipment for roasting furnace tail gast operation, and helps customers to deeply understand the product production process and production site, and gain favorable comments and recognition from customers.。

Flue gas denitrification equipment for roasting furnace tail gas

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.。
