The Chiyoda CT-121 demonstration project, being conducted at Georgia Power`s Plant Yates` 100 MWe Unit 1, is an evaluation of a unique wet-limestone, forced-oxidized FGD process and is a part of the Innovative Clean Coal Technology (ICCT) program. The CT-121 process uses a single unique absorber vessel made entirely of fiberglass reinforced plastics called a jet bubbling reactor (JBR). The JBR allows concurrent completion of all the necessary reactions to remove sulfur dioxide from the flue gas and to precipitate a gypsum byproduct. This paper will discuss the results of the low-particulate test phase, including the effects of higher-sulfur coal, as well as initial results from the high-particulate test phase (existing electrostatic precipitator deenergized). DOE-sponsored air toxics testing has also been conducted, but final results were not available at the time of this writing. A discussion of limestone selection and its impact on the dewatering properties of the CT-121 gypsum byproduct is also included. Performance results emphasize the efficiency, reliability, and flexibility of the CT-121 process. Preliminary testing of the CT-121 process at Plant Yates has produced excellent performance results. The process has proven itself capable of exceeding its design SO{sub 2} removal efficiency specification of 90%, both with and without the ESP in service. The process has also achieved SO{sub 2} removal efficiencies of greater than 98%. Particulate measurements, conducted with the ESP deenergized, have established the capability of the CT-121 process to remove over 99% of the boiler`s particulate emissions at 100% boiler load.
