The report gives results of an evaluation of fabric filtration on Boiler 108. The operating characteristics of the reverse-air baghouse controlling emissions from Boiler 108 were determined via data (collected by Navy personnel) on boiler and baghouse operation (hours of operation, coal feed rate, steam load, air load, baghouse inlet temperature, and baghouse module pressure drop), and periodic inspection and testing of selected bags. Tests of physical characteristics of the fiberglass bags revealed normal deterioration of fabric strength with increasing time of exposure to flue gas. Fill fibers were more affected than warp fibers. A long plateau in bag life was observed; fabric characteristics after 1500 hours of actual operation and after 7600 hours did not differ greatly. Statistical analyses of fabric test data indicated effects on fabric due both to length of exposure time and position in the baghouse, and interaction of those effects. Other analyses indicated that exposure time was the dominant effect. Operating costs for reverse-air and induced-draft fans were calculated for 1983, 1984, and 1985.
