This report discusses the results of a field investigation of full-scale baghouses collecting fly ash at five coal-fired power plants. All five plants burned western, low-sulfur, subbituminous coal and were equipped with baghouses cleaned by reverse gas. Since all of the baghouses operated with clear stacks, particulate collection efficiencies were not measured. Instead, attention was focused on parameters associated with pressure drop, which is important because it is directly related to operating and capital costs. Cleaning-cycle information was taken at the baghouses, and measurements were made of air-to-cloth ratio and tube sheet pressure drop. In addition, seasoned bags and bag samples cut from seasoned bags were weighed to determie dustcake areal loading. Average drag (presure drop/air-to-cloth ratio) and drag measured using these bag samples were recorded. Also, data on the chemical analysis of the coals and their resultant fly ash were gathered, and particle size distribution measurements were made on fly ash samples. Electrical resistivity was measured on fly ash from three locations. 8 refs., 33 figs., 38 tabs.
