This program, co-funded by the US Environmental Protection Agency and the Electric Power Research Institute, has resulted in an evaluation of a full-scale utility spray dryer/baghouse dry FGD system. The system is installed at the Northern States Power Company's Riverside Station and treats flue gas from a nominal 100 MW of coal-fired power generation. This has been the first independent evaluation of a full-scale spray dryer/baghouse system. For the test program, two different coals were used as boiler fuels. One coal was a subbituminous coal and coke mixture with a nominal 1.2% sulfur content. The second was a 3.4% sulfur Illinois bituminous coal. The test program was conducted from July to October 1983. SO/sub 2/ removal, particulate emissions, sulfuric acid removal and extensive process data were recorded. Low sulfur coal tests indicated that 75% SO/sub 2/ removal was achievable in the short-term at reagent ratios of 0.6 to 0.7, and 90% SO/sub 2/ removal was achievable at a reagent ratio of about 0.8. An average removal of nearly 90% was achieved in short-term tests with high sulfur coal at reagent ratios of 1.3 to 1.4. Calcium chloride addition to the atomizer feed slurry was found to reduce the lime addition requirements for high sulfur tests by approximately 25%. 19 refs., 38 figs., 64 tabs.
