Flue gas denitrification engineering

We have mature SCR denitrification technology, such as medium to high temperature SCR denitrification technology, medium to low temperature SCR denitrification technology, and ultra-low temperature SCR denitrification technology, which are widely used in industries such as coke ovens, steel sintering, lime kilns, gas boilers, heating furnaces, hot blast furnaces, papermaking, industrial silicon, and waste incineration< Br> For high-temperature industrial kilns that undergo chemical or physical reactions and release a large amount of gas during roasting, calcination, and drying of ores, our company has developed a dedicated SCR denitrification system for lime kilns, which uses an induced draft fan to extract and treat high-temperature dusty flue gas from 160 ℃ to 280 ℃< Br> Processing air volume: 1-1 million meters ³/ H
Main equipment: denitrification reactor, catalyst, ammonia injection system, metering system, etc Scope of application: Various kiln flue gas denitrification industries

Dust removal process at the kiln end of the lime industry
The temperature of the flue gas at the end of the lime kiln is between 150 and 280 ℃. Based on the characteristics of lime production and smoke and dust, and drawing on years of experience, our company adopts ultra-low temperature SCR denitrification for kiln denitrification. The entire system is operated under negative pressure and sealed well. The purified gas is discharged into the atmosphere through a high-temperature resistant fan through the chimney. The concentration of nitrogen oxides in the purified gas can be controlled at 30mg/Nm ³ Within, better than standard.




Taking 75000 Nm3/h kiln flue gas treatment as an example, the comparison of equipment configuration and energy consumption with medium and low temperature SCR denitrification technology is as follows (estimated based on annual operation of 8000 hours):
