Dust Collector Bags: Dust on tubesheet

An excessive amount of dust on the clean side of the tubesheet is both an indication of a problem and a problem itself. Excessive dust on the tubesheet can be caused by:

• bags not properly installed
• poor cellplate fit (top loader)
• loose clamps (bottom loader)
• mismatched filter media to dust
• overcleaning
• failures in bags (holes, rips, tears, stitching failures)
• cracks in tubesheet on welds attaching
0tubesheet to walls
• poor prior maintenance

Excessive dust on the tubesheet can also cause:

• excessive emissions from the stack
• premature bag failures due to abrasion by the cleaning system and/or dust build up inside the bags
• bags installation and removal problems
• corrosion and scaling of the tubesheet

Remedies for these problems include:

• using professional baghouse maintenance

• investigating and installing bags designed to
0separate the dust at the highest efficiency level
