Introduction to Denitrification of flue gas outside the furnace, advantages, characteristics and principles of SCR denitration

Denitrification of flue gas outside the furnaceit refers to the process of removing nitrogen oxides from flue gas to reduce environmental pollution. NOx is a pollutant harmful to the atmospheric environment, which has strong irritation and toxicity, and will lead to environmental problems such as acid rain and photochemical smog, and also endanger human health. The main principle of flue gas denitrification technology is to reduce NOx to nitrogen and water by adding appropriate reducing agent or catalyst in the combustion process or flue gas treatment system, so as to reduce NOx emission.，widely used incoal-fired power station,Gas power plant,building materials,coal-fired power station,cement plant and other industries，favorable price。

These industries will produce a large number of NOx emissions in the production process, and the Denitrification of flue gas outside the furnace technology can provide effective denitrification solutions for them. In addition, the gate technology can be adjusted and optimized according to different flue gas components and emission requirements to meet different denitration requirements.、Intelligent control is gradually realized. By integrating advanced control system and sensor technology, the Denitrification of flue gas outside the furnace 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.、There are many kinds of catalysts used in the technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at a lower temperature. At the same time, the active components and carrier materials of the catalyst are constantly being developed and improved to improve its catalytic efficiency and service life. This enables the Denitrification of flue gas outside the furnace technology to maintain efficient denitrification capability in a wider temperature range and more complex flue gas conditions.、It is famous for its high-efficiency denitration ability, which can usually reach more than 90% denitration efficiency. This means that the Denitrification of flue gas outside the furnace 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 is mainly due to the promotion of the catalyst, which makes the chemical reaction between reductant and NOx more rapid and thorough.，There are many kinds of catalysts used in the technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at a lower temperature.

3、Denitrification of flue gas outside the furnace principle

Denitrification of flue gas outside the furnacein 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.，modern technology，favorable price。
