- Abstract
- A theoretical model for mass penetration through a pulse-jet cleaned fabric filter as a function of particle size was evaluated. Particle penetration data were collected for 24 different operating conditions of a three-bag, pilot-scale filter using polyester felt fabric bags with a rough untreated surface or a smooth ptfe-laminated surface. Each bag filtered limestone dust or fly-ash for 30, 120, or 480 seconds and was then cleaned either on-line or off-line. The fabric bags were conditioned by 150 cleaning cycles before data were collected. The model was analyzed for 13 particle diameters along a geometric progression of sizes ranging from 0.10 to 6.7 um. Model parameters were found to be strongly dependent on particle size. Fabric surface treatment significantly affected filter performance. Fabric cleaning mode and cleaning pulse cycle time were not significant. Model variation with dust type is not clear. The model predicted results for an independent data set well. Fabrics should be well conditioned with dust for the model to predict outlet mass flux adequately.
