SCR honeycomb low-temperature denitrification catalyst

SCR honeycomb low-temperature denitrification catalystTechnical measures.

1. Control the quality of coal entering the furnace and choose coal with low sulfur and low ash content. Coal with high sulfur content will cause an increase in sulfur trioxide after catalysis, while coal with high ash content will exacerbate catalyst blockage.

2. On the premise of ensuring that the concentration of nitrogen oxide emissions meets environmental requirements, minimize the amount of ammonia injection as much as possible.

3. Strengthen monitoring of ammonia escape concentration in the tail flue. If the concentration is higher than 10ppm, the automatic logic should be modified and the ammonia injection amount should be appropriately reduced.

4. Strengthen the monitoring of pressure difference in the air preheater and increase the frequency of soot blowing in the air preheater. If the pressure difference irreversibly increases, the amount of ammonia injection should be reduced.

5. Strengthen the pressure difference monitoring of the denitrification reactor and maintain the continuous operation of the sonic soot blower.

6. Catalyst manufacturers calculate the amount of ammonia injection based on the low-temperature correction curve.

7. Measures to increase the inlet flue gas temperature of SCR reactor.

Honeycomb shaped SCR low-temperature denitrification catalyst formula *, innovative process, flexible SCR reactor layout, suitable for various flue gas projects, not affected by boiler and other flue gas conditions. The selected active component is a vanadium free catalyst, which will not cause secondary pollution to the environment. The catalyst exhibits good sulfur and water resistance, stable operation, and reliable catalyst life, making the flue gas purification process more reasonable. At the same time, energy consumption, operating costs, and one-time investment are significantly reduced.

SCR honeycomb low-temperature denitrification catalystIt can treat nitrogen oxides (NOx) in exhaust gas to meet national or local environmental emission standards. The main application areas include denitrification of generator sets, nitrogen oxide treatment of distributed energy, SCR denitrification of gas turbines, medium temperature denitrification of biomass combustion, and high-temperature denitrification treatment of industrial waste gas. Can treat the denitrification of organic waste gas generators in farms.
