What are the materials of coal-fired filter bags?

There are usually several types of materials for coal-fired filter bags:

Polyester filter bag: Polyester filter bag is a commonly used filter bag material that has high strength, wear resistance, tensile resistance, corrosion resistance, and can withstand high temperatures and chemical corrosion.

Polyester filter cloth bag: polyester filter cloth bag has excellent heat resistance and chemical stability, suitable for high temperature, high humidity and other harsh working environments, and can effectively filter the small particles in the flue gas.

Sintered filter bag: Sintered filter bag is made of multi-layer fine fiber material through sintering process, which has good corrosion resistance, temperature resistance, wear resistance, and filtration performance, and is suitable for filtering high concentration flue gas.

Glass fiber filter bag: Glass fiber filter bag is a filter bag material that is resistant to high temperature, corrosion, and wear. It is suitable for filtering high-temperature flue gas and has good filtration efficiency and long service life.

Ceramic filter bag: Ceramic filter bag has characteristics such as high temperature, corrosion resistance, and wear resistance, which can effectively filter particulate matter and microorganisms in flue gas. It is a relatively advanced filter bag material.
