New fabric laminate mitigates flyash collection woes
This article describes how adding a membrane to a well-known top-performing fabric has enhanced its flex strength. Save an erosion problem at the bag bottom, the new material has greatly eased flyash collection at a coal-waste-fired CFB boiler plant. The laminate is a significant development for woven fabrics. This new fabric composite uses the well-known Gore-Tex membrane, applied at many powerplants with difficult-to-collect flyash, for filtration while the laminate greatly enhances the fabric`s overall flexibility. This, in turn, reduces bag wear from pulsing. This composite material also improves dust-release characteristics, thus allowing the unit to operate at lower cleaning pressure (that is, 50 psi). Additionally, these bags can withstand operating temperatures up to 500 F.
