1. Long process parameters are difficult
2. Hazardous chemicals
3. There is a large demand for personnel
4. Occupational exposure risk
5. Low acid removal efficiency of slaked lime
6. The residue contains crystal water, and the production is large
7. Zero discharge of sewage is difficult
8.SCR heating investment and energy consumption is high
9. More serious corrosion/blockage, FPR material overtemperature fire risk
10. The system resistance is high, and the fan power consumption increases
11. The overall investment is large and the comprehensive cost is high
12. Policy risks: Shanghai, Zhejiang, Shanxi, Liaoning, Shaanxi and other local standards for coal-fired power Plant air pollutant emission standards have clearly required: there must be smoke temperature control and other effective measures to eliminate gypsum rain, colored smoke rain, etc
1. Simplified process, reduced parameters and reduced difficulty
2. The complexity and danger of washing are eliminated
3. Reliable operation, easy adjustment, less maintenance
4. Cleaner environment and less occupational exposure
5. It can meet the strict environmental emission standards of Europe and America
6. Improved efficiency, less residue
7. No waste water is generated
8.SCR heating energy is reduced
9. The system resistance is reduced, and the fan energy consumption is reduced
10. Effective removal of SO3, HCl, HF
11. Helps eliminate smoke plumes
12. Better investment and operating costs
1) Use your existing bag filter – just replace the bag
Less adjustment of process and operation
No extra space required
Does not increase the pressure difference
Easy to install and maintain
2）It is also ideal for new factories
Simplify flue gas purification process
Save energy cost
Reduce equipment investment costs
