This report compares the operating and maintenance costs, and equipment capital costs of fabric filter (F) and electrostatic precipitator (ESP) systems for typical 500 MW units meeting a range of particulate emission limitations and firing fuel from fuel (5) major coal and lignite fields. To meet the current New Source Performance Standard 0.03 lbs/10/sup 6/ Btu, ESPs and FFs were found to be economically equivalent for the more precipitable ash from high- to medium-sulfur, eastern coals and North Dakota lignites. The fabric filter is the economic choice for the low-sulfur, western coals investigated in this report. Irrespective of coal and ash properties, a conventional reverse-gas FF with an air-to-cloth ratio of 2.0 ft/min was found to be the economic choice over an ESP with a specific collecting area greater than 500 ft/sup 2//1000 ACFM. This report also examines the cost benefits of applying advanced technology and optimized designs to FFs and ESPs. For example, the levelized costs of a conventional reverse-gas FF can be reduced by increasing the air-to-cloth ratio above the conventional design valve of 2.0 ft/min, with a minimum cost calculated near 2.7 ft/min. Other technologies investigated are shake/deflate and sonic cleaning of FFs, and gas conditioned ESPs. The sensitivity of a particulate collection system's cost estimate to such factors as air-to-cloth ratio, bag life, and power consumption is also demonstrated. 29 refs., 46 figs., 53 tabs.
