High-Performance PPS Filter Bags for Coal-Fired Boilers | Xiechang®
Xiechang utilizes a specialized Japanese-imported three-needle and six-thread sewing unit to manufacture high-precision filter bags. This advanced equipment ensures superior durability for various geometries, including round, trapezoidal, flat, and custom-profiled designs tailored to specific industrial requirements.
For coal-fired boiler applications, our PPS (Polyphenylene Sulfide) filter media provides the ideal balance of thermal stability and chemical resilience.
Technical Performance: PPS Filter Media
Our PPS dust collection bags are engineered to handle the corrosive flue gas environments typical of power generation.
-
Operating Temperatures: Sustains a continuous running temperature of 160°C, withstanding peak surges up to 190°C.
-
Chemical Resistance: Features excellent resistance to acids, alkalis, and oxidation, ensuring long-term integrity in sulfur-rich environments.
-
Structural Strength: Delivers a warp stretch strength of 900 and weft stretch strength of 1200 for high-pressure pulse cleaning cycles.
-
Air Permeability: Maintains an optimal flow rate of 15 M³/M².S @ 200Pa.
