Abstract
Pulse-jet fabric filters have captured an increasing share of the industrial air filtration market and currently make up half the fabric filter sales in the United States. (1) Part of the reason for their popularity is that pulse-jet filters operate with an air to cloth ratio, or superficial filtration velocity, substantially higher than that used in a filter cleaned by other means. As a result, pulse-jet filters are more compact and may be less expensive to purchase, although the cost for compressed air used in pulse cleaning can be appreciable. The report gives results of an economic analysis of pulse-jet filtration. It shows that, if the device is operated continuously, the filtration velocity associated with least total annualized cost is about 3 cm/s (6 ft/m). As annual operating time decreases, operating costs decrease; however, fixed cost remains about the same. Although the analyses depend on the particular values for cost factors used in the economic model, the least cost trend of increased velocity with decreased operating time should stand, regardless of the values used. As filtration velocity increases, penetration also increases. Experiments determined that essentially all penetration through the filter is due to seepage, and that almost no particles penetrate straight through without stopping.
