TECHNOLOGICAL PROCESS
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.
OPERATING COST ANALYSISI
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):
