How to Extend Fiberglass Filter Bags Service Life

What Are Fiberglass Filter Bags Used For?

Fiberglass filter bags are an essential component in many high-temperature industrial dust filtration systems. Thanks to their excellent heat resistance (up to 260–300°C) and dimensional stability, they are widely used in:

  • 🏭 Cement kilns – For dust capture in preheaters and clinker coolers
  • 🔩 Steel plants – In sintering and electric arc furnace emissions
  • Coal-fired power plants – For boiler flue gas filtration
  • 🧪 Chemical industries – Handling corrosive off-gases
  • 🔥 Waste incinerators – Filtering acidic, high-temperature exhaust

What Affects the Lifespan of Fiberglass Filter Bags?

Although fiberglass filter bags are durable, their service life can be significantly reduced by improper use. Key influencing factors include:

  • 🔥 Temperature overshoot: Going beyond thermal limits causes fiber shrinkage or brittleness
  • 🧪 Acid gas corrosion: Exposure to SO₂, HCl, or HF can degrade fibers
  • 💧 Dew point and condensation: Acid dew formation causes surface damage
  • 🌀 Abrasion from dust: Sharp or high-velocity particles wear down the fabric
  • 🧼 Improper cleaning: Excessive pulse jet pressure leads to mechanical failure

How to Maximize Their Service Life?

To make the most of fiberglass filter bags, here are some best practices:

  • Use PTFE coated or laminated fiberglass for enhanced chemical and temperature resistance
  • Control gas temperature to avoid overheating or condensation near dew point
  • Improve pulse cleaning settings, avoiding over-pressurization
  • Design proper cages and airflow to reduce mechanical stress
  • Schedule regular inspections to detect early signs of clogging or wear
