Mass penetration through a pulse-jet cleaned fabric filter was evaluated as a function of particle size. The fabric bags were conditioned by 150 cleaning cycles before data were collected. Particle penetration data were collected over 24 different operating conditions for a three-bag, pilot-scale filter using polyester felt bags with either a rough, untreated surface or a smooth, polytetrafluoroethylene-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 applicability to these data of the Leith and Ellen becker (1980) model for outlet mass flux through a filter was analyzed for a geometric progression of 13 particle diameters from 0.10 to 6.7 μm. Model parameters were found to be strongly dependent on particle size and on fabric surface treatment but were not affected by fabric cleaning mode or cleaning cycle time. Dust type may have affected filter performance but the effect was not significant statistically. After the model had been calibrated using the present data set, it was used to predict results for an independent data set and performed reasonably well. Model parameters may be sensitive to the degree to which bags are conditioned with dust. |
