The report gives results of a full-scale investigation (following a pilot plant study) of applying high-velocity fabric filtration to coal-fired boiler fly ash control. Two filter systems were applied separately to two 60,000 lb steam/hr coal-fired boilers. Performance evaluated over a year included total mass removal efficiency and fractional efficiencies. One filter system used Teflon felt as the filter medium; the other used Gore-Tex, a PTFE laminate on PTFE woven backing. During the year, a limited number of glass felt and woven glass bags were introduced into the house containing Gore-Tex. Installed, operating, and annualized costs were computed for five filter media (Teflon felt, Gore-Tex PTFE laminate, two weights of woven glass, and a felted glass fabric) in a fabric filter systems capable of handling 70,000 acfm. The lighter weight woven glass fabric is the least expensive filter medium overall and (assuming that a 4-year bag life is feasible) this makes fabric filtration an economically attractive alternative to electrostatic precipitation. The 15 oz woven glass fabric had a projected annualized cost of $0.36/acfm at an air-to-cloth ratio of 5.8/1.
