The report gives results of a pilot-scale investigation to determine the techno-economic feasibility of applying fabric filter dust collectors to solid refuse fired boilers. The pilot facility, installed on a slipstream of a 135,000 lb/hr boiler, was sized to handle 9000 acfm at an apparent filtering velocity of 6 fpm. Filter media evaluated included a woven glass, a felted glass, and a PTFE laminate on a woven backing. The three filter media had overall efficiencies greater than 99.8%, at apparent filtering velocities of 6 fpm or less, with an inlet loading of 0.5 gr/dscf. For the brief exposures during performance testing, none of the bag materials showed any wear problems. Installed costs for a woven glass fabric filter (the least expensive material tested) capable of handling 140,000 acfm were $317,000, $422,000 and $817,000 ($2.26, $3.01, and $5.83/acfm, respectively) at corresponding air-to-cloth ratios of 8.9, 5.8, and 2.9. Installed, operating, and annualized costs for other filter media, as well as costs for electrostatic precipitation and wet scrubbing, are also presented.
