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

3、SCR low-temperature flue gas denitrification system performance advantage

The advantages of SCR low-temperature flue gas denitrification system are as follows:

The high-efficiency denitration ability of SCR low-temperature flue gas denitrification system technology can significantly reduce the environmental emission cost of enterprises and avoid fines and legal risks due to illegal emissions. In addition, SCR low-temperature flue gas denitrification system technology can also reduce operating costs and improve the economic benefits of enterprises by recycling heat energy.

4. Mature and stable technology

SCR low-temperature flue gas denitrification system technology has been developed and applied for many years, and the technology is mature and stable. The SCR low-temperature flue gas denitrification system has high reliability and stability, and can maintain stable denitrification efficiency under various working conditions. In addition, the SCR low-temperature flue gas denitrification system technology has good adaptability and adjustability, and can be adjusted and optimized according to different flue gas components and emission requirements.

5. Diversity and high efficiency of catalysts

There are many kinds of catalysts used in the SCR low-temperature flue gas denitrification system technology, including vanadium-based catalysts and titanium-based catalysts, which can promote the chemical reaction between reductant and NOx at low 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 SCR low-temperature flue gas denitrification system technology to maintain high efficiency of denitration in a wider temperature range and more complex flue gas conditions.
