SNCR

Technical characteristics

Advantage:

1. Simple system and low investment cost: No need for expensive catalysts and bulky reactors, small footprint.

2. Short construction period and easy renovation: It is especially suitable for denitrification of existing boilers/kilns.

3. Relatively low operating costs: The main consumables are reducing agents, and there are no catalyst replacement costs.

4. Low pressure loss: It has little impact on the normal operation of the boiler system.

summary

SNCR technology is an economical and practical medium and low temperature denitrification technology, and its principle relies on selective chemical reactions at high temperatures. Its successful application relies heavily on precise control of the temperature window and adequate mixing of the reducing agent with the flue gas. Although its denitrification efficiency is not comparable to that of SCR technology, its advantages of low investment cost and simple system make it still have a wide range of market and application value in specific fields, especially in small and medium-sized combustion equipment and as a primary or auxiliary measure for denitrification. In practical applications, the combined process of "SNCR+SCR" is often used to take into account both economy and high efficiency.
