Dedusting engineering for denitrification and desulfurization of 2 x 260 t/h air separation boiler for enterprise |
|
| This project adopts high ash type selective catalytic reduction flue gas denitrification (SCR) process. The denitration efficiency in operation of any unit is greater than or equal to 82.53%; the escape of NH3 is less than 3ppm; the conversion rate of SO2/SO3 is less than 1%; it has a service life of 30 years. After the renovation project was completed, the NOx concentration decreased from 515 mg/ M3 to 90 mg/m3, with emission concentration meeting the "thermal power plant air pollutant emission standards" (GB13223-2011) in coal-fired boiler air pollutant emission limits in particular 100mg/m3. If the existing engineering equipment annual utilization hours is 8000 hours, the annual emissions of NOx will be reduced by 1506 t. |
