This report describes operations at EPRI's low-sulfur coal Fabric Filter Pilot Plant during the first 19 months following its startup in October 1980. The primary objectives of this operating period were to collect data to characterize the FFPP as a research tool, and to determine the effects of varying some of its basic operating parameters. The major parameters varied included the method of bag cleaning, the concentration of fly ash at the inlet, the length of the filtering period, and the filtering air-to-cloth ratio. The principal criteria of performance were the tubesheet pressure drop and the efficiency of fly ash collection. Major emphasis was on reverse-gas cleaning. Results of tests indicate that the structure and properties of the residual dustcake on the bags are the dominant factors determining pressure drop. Also, a long period of time - perhaps up to a year or longer - appears to be necessary for reverse-gas cleaned baghouses to achieve stable operation in terms of pressure drop. A limited evaluation of shake/deflate cleaning indicated that this alternative offers the potential of lower pressure drop than reverse-gas cleaning. Numerous measurements of inlet and outlet fly ash concentration and particle size distribution showed collection efficiencies usually above 99.99% with reverse-gas cleaning and just slightly less with shake/deflate cleaning.
