The Tennessee Valley Authority, in cooperation with the Electric Power Research Institute and Ontario Hydro, evaluated a 10-MW spray dryer/electrostatic precipitator (SD/ESP) on flue gas derived from the burning of high-sulfur (approximately 4 percent) coal. The main objective of the testing was to determine the effect of the major variables on SO/sub 2/ removal efficiency and whether the spray dryer could be retrofitted before an existing ESP to meet SO/sub 2/ and particulate emission limits. Major variables affecting SO/sub 2/ removal are the approach-to-saturation temperature, lime stoichiometry, and spray dryer inlet flue gas temperature. In addition, some preliminary screening tests with an alternate lime, an alternate higher chloride coal, and a different feed system design were run. These screening tests seemed to show enhanced SO/sub 2/ removal for these alternatives, which will be evaluated further. Carbon steel and Cor-Ten A are adequate materials of construction for this facility provided necessary precautions are made to avoid air in leakage which could allow cold spots, resulting in condensation and increased corrosion. Sufficient insulation on metal surfaces is also necessary. 62 figs., 30 tabs.
