Title: Final results for the EPRI-DOE-SCS Chiyoda Thoroughbred CT-121 clean coal project at Georgia Power`s Plant Yates

Conference ·
OSTI ID:324753

The Yates Clean Coal Project was a co-funded Clean Coal Technology effort, sponsored by the US Department of Energy, the Electric Power Research Institute and Southern Company Services (EPRI-DOE-SCS) to evaluate a retrofit wet-limestone-based, sulfur dioxide (SO{sub 2}) scrubbing system in treating the hot flue gases of a coal-fired, 110MW electric utility boiler. This Project tested the operational limits of Chiyoda`s CT-121 Jet Bubbling Reactor System (JBR ) at Georgia Power`s Plant Yates from 1992 through 1994. Although the original test plan called for a very conservative assessment, the CT-121 system proved robust, so it was tested at widely varying conditions. Fuel sulfur content was varied between 1.5% to 4.3%, various limestone sources at several grind sizes were used, particulate removal and air toxics performance were measured and by-product gypsum soil amendment experimentation was conducted. In all cases, the CT-121 system gave encouraging results with predictably high SO{sub 2} removals (95--99%) and particulate removals (99+%) at all conditions with high reliability. Closed loop operations (no liquids treated, none discharged) called for the extensive application of corrosion impervious, fiberglass reinforced plastics (FRP) that was also very successful. Gypsum by-product proved to be significant as a soil enhancement and was granted a plant food license by the State of Georgia. So far, the Yates Project has received several awards from industry and environmental groups for its performance including Power Plant of the Year in 1994 from Power magazine.
