Since February 1982, the Electric Power Research Institute has been conducting a test program on a 2.5 MW equivalent spray dryer/fabric filter FGD pilot unit. The goals of the program have been to confirm the capabilities of the spray dryer FGD process and to provide the electric utility industry with design and operating information for spray dryer/fabric filter systems. The pilot unit treats 5000 to 9000 acfm of flue gas from the Public Service of Colorado Arapahoe Station. The spray dryer is 10 feet in diameter and is equipped with a rotary atomizer. The fabric filter is a reverse gas cleaning unit, and uses 36 full-size (12 inches by 35 feet) fiberglass bags with a Tricoat finish. This report documents results from February 1982 through August 1983. Most tests have been conducted with lime reagent, and mostly with fabric filter solids recycle rather than once-through operation. Inlet SO/sub 2/ concentrations of 350 ppM and 1000 ppM have been tested during this period. Variables studied have included Inlet SO/sub 2/ concentration, flue gas flow rate, reagent ratio (lbs recycle solids per lb fresh lime solids), approach to adiabatic saturation at the dryer outlet, atomizer feed configuration and system makeup water composition. 24 refs., 84 figs., 41 tabs.
