Pulse-jet filters are commonly used for both dusts and fumes. These filters have the gas flow from outside to inside through internally supported bags of felted rather than woven fabric. Dust is deposited on the outside of the bag. The... [Pg.1235]

For pulse-jet filters, the operating pressure drop is given approximately by the following equation ... [Pg.1242]

Cleaning by reverse-flow pulses of high pressure air is normally applied to fabric filters and to pleated cartridge collectors alike. The high pressure pulses may be created by a pressure blower or come directly from a compressed air supply. In the latter case the type is normally called a pulse-jet filter. [Pg.408]

Fabric filters are limited by physical size and bag-life considerations. Some sacrifices in efficiency might be tolerated if higher air-cloth ratios could be achieved without reducing bag life (improved pulse-jet systems). Improvements in fabric filtration may also be possible by enhancing electrostatic effects that may contribute to rapid formation of a filter cake after cleaning. [Pg.2196]

Fabric filters have had a long history in performing effectively in a wide variety of applications. Common applications using pulse-jet cleaning systems include ... [Pg.405]

Cost estimates are presented below for pulse jet cleaned fabric filters. The eosts are expressed in fourth quarter 1998 dollars. The cost estimates assume a conventional design under typical operating eonditions and do not inelude auxiliary equipment... [Pg.407]

Cartridge collectors perform very effectively in many different applications. Common applications of cartridge filter systems with pulse jet cleaning are comparable to baghouses described earlier. In addition to these applications, cartridge collectors can be used in any process where dust is generated and can be collected and ducted to a central location. [Pg.412]

Figure 13.17 shows isometrics of mechanical shaking, reverse air, cartridge, and pulse-jet types of bag filter units. [Pg.1239]
