1、Brief introduction of High temperature SCR denitrification

High temperature SCR denitrificationis an efficient, stable and environment-friendly flue gas denitrification technology.，at runtime,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.，Commonly used inImprove product quality,Meet the requirements of environmental protection,Promote sustainable development,Meet the requirements of environmental protection,environmental protection and so on，it has the characteristics of Environment friendly, Strong adaptability, Strong adaptability, Stable operation and Stable operation，is a High temperature SCR denitrification。

2、High temperature SCR denitrification principle

High temperature SCR denitrificationCatalysts 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 mostly used in Flue gas denitrification, Improve product quality, Improve product quality, Meet the requirements of environmental protection, Promote sustainable development, Flue gas denitrification and so on，widely used inGas power plant,cement plant,coal-fired power station,building materials,metallurgy and other industries，it is widely used inGas power plant,building materials,cement plant,iron and steel plant,metallurgy and other industries，support customization。
