New Filter Bags Should Have New Bag Accessories

When you need bags for your collector, don't overlook the accessories. Not ordering them is usually false economy. New bags won't stop emissions without new seals or gaskets to help seal them to the tubesheet for a leak-free fit.

Old venturis may be showing signs of wear as well, and may even be the cause of bag abrasion. A misaligned blowpipe can direct the pulsed air against the side of the venturi rather than right down the middle of the bag, eventually wearing a hole in the metal and ultimately causing bag damage. Check your tubesheet for cracks and leaks that could be causing problems. Burrs can snag bags during installation, and holes that are not perfectly round can be a source for leaks.

Before replacing bags, a technical inspection by GE baghouse specialists can prevent delays in getting the unit back online. If problems exist beyond simple bag replacement, they can be identified and a plan formed to get your equipment back in operation to meet air pollution control requirements.
