In high-temperature environments like coal-fired boiler plants, the choice of dust collector bag material is crucial. For coal-fired boiler dedusting, PPS needle felt bags are a suitable option due to their temperature resistance of up to 190 degrees Celsius and good corrosion resistance. Alternatively, polyester dust bags are a cost-effective option for use under normal temperature conditions.
Baghouse dust collectors are commonly used for coal-fired boiler dedusting. For such applications, I recommend using PPS high-temperature and corrosion-resistant dust filter bags. This recommendation is based on the widespread use of baghouse dust collectors in power plants since the 1980s, particularly in industrial plants in countries like the United States, Canada, Australia, Germany, and the United Kingdom. These baghouse systems boast a dust removal efficiency of over 99.9%, ensuring effective dust handling.
In China, baghouse dust collectors are widely used in industries such as mining, cement, metallurgy, grain processing, and machinery manufacturing. However, in the power generation sector, baghouse dust collectors are primarily limited to single-machine applications in coal conveying and pneumatic ash removal systems. They have not seen substantial application in the tail-end dedusting of power station boilers.
PPS needle felt is a filtration material made by needling PPS (polyphenylene sulfide) fibers, offering long-term usage at temperatures around 190 degrees Celsius. PPS fibers, also known as polyphenylene sulfide fibers, exhibit excellent chemical stability and strength due to their unique molecular structure.
PPS needle felt finds applications in various industries, including waste incineration power plants, cement kilns, blast furnaces in steel plants, foundries, chemical plants, carbon black plants, aluminum plants, copper plants, and ferroalloy plants, for dust recovery and smoke filtration at the forefront and tail-end of production processes.
