The choice of dust bag for power plants directly impacts whether operations comply with environmental requirements. Coal-fired power plants, biomass power plants, and waste incineration power plants all require dust removal. Because different combustion media produce varying flue gas compositions, the choice of dust bag must be tailored to the specific application.
Power Plant Dust Collection Bag Materials
PPS Dust Collection Bags
They have excellent heat resistance and can work continuously in a 200℃ steam environment, with an instantaneous temperature resistance of up to 240℃. They also feature good chemical stability and can resist corrosion from most acids, alkalis, and organic solvents, except for strong oxidants, hydrofluoric acid, and phosphoric acid. These bags are suitable for high-temperature flue gas dust collection in coal-fired boilers, waste incinerators, power plants, and other scenarios.
PPS+PTFE Membrane Dust Collection Bags
These bags retain the high-temperature resistance and wear resistance of PPS fibers, while adding hydrophobic properties. They reduce resistance and improve filtration efficiency, making them suitable for treating gases with high viscosity, easy condensation, or high water content.
PTFE Dust Collection Bags
Among commercial polymers, they have the best chemical resistance and corrosion resistance. They also offer good hydrophobicity, chemical stability, weather resistance, and a long service life. Capable of resisting strong acids, strong alkalis, oxidants, and salt solutions, they also have excellent friction resistance and wear resistance. They are suitable for high-temperature flue gas dust collection in waste incinerators, coal-fired boilers, and other equipment.
Aramid Dust Collection Bags
Made of high-performance synthetic fibers, they have high strength, high modulus, high-temperature resistance, chemical corrosion resistance, and radiation resistance. Even under high-temperature, high-pressure, and high-humidity conditions, they can still maintain good filtration performance and wear resistance, and can be used for high-temperature flue gas dust collection in various scenarios.
Glass Fiber Dust Collection Bags
Belonging to inorganic non-metallic fiber materials, they have excellent high-temperature resistance, electrical insulation, and chemical stability. The coated version is composite with expanded microporous PTFE film on the base cloth, which provides better filtration performance and hydrophobicity. These bags are suitable for treating high-temperature, high-pressure, and high-humidity flue gas.
