Coal-Fired Boilers
PPS (Ryton) chemistry resists sulfuric acid mist and SO₃ excursions that destroy polyester in coal boiler polishing bags.
PPS Needle Felt
Material Type
PPS Needle Felt
PPS needle felt filter media engineered for high-temperature industrial dust collection applications, providing excellent chemical stability, sulfur resistance, and strength retention in acidic flue gas environments such as coal-fired boilers, waste incineration, and metallurgical processes.
Benefits
- Sulfuric environment specialist — coal boilers, incinerators, and smelters
- Low pressure drop maintenance — stable pores extend fan life
- Long-term durability — resists chemistry that destroys other fibers within months
Suitable Equipment
- High-temperature baghouse systems
Segmentation
Power Plants
Maintains stable ΔP in utility and industrial power boilers where upset conditions spike dew points across the acid point.
Waste Incineration Facilities
Handles halogenated flue gas species and acidic ash from RDF and MSW lines better than commodity felts in the same temperature envelope.
Industrial Filtration Requiring Acid-Resistant Performance
Catch-all segment for smelters, roasters, and chemical dryers where combined acid + temperature demands PPS blends.
