Biomass Furnace Dust Filtration - Air and Climate - Air Pollution Treatment

Application: PPS (Ryton) Filter Bags are widely used in coal-fired boilers, waste incinerators, coking furnaces, kiln furnaces,Biomass Furnace ,chemical dry process of flue gas cleaning processes, also using, carbon black, powder collection, pneumatic conveying, cement industry, and more. When due to chemical attack and hydrolysis causes, Aramid cannot be used, PPS (Ryton) Filter Bag can be substituted.


  • Continuous gas continuous temperature is up to 160°C, instant heat resistant up to 200°C
  • Chemical structure is simple, strong and stable 
  • Excellent performance of acid and alkali resistance!
  • Excellent hydrolysis resistance capability, and strong chemical stability
  • Good flame retardant and excellent heat resistance function
  • Disadvantage is that antioxidant performance of PPS (Ryton) Filter Bag is poor, it reacts to oxidation-corrosion. It is suitable for gas with O2 composition < 10%
