Alternate fuel testing at the Wabash River coal gasification repowering project
The Wabash River Coal Gasification Repowering Project, utilizing Dynegy's coal gasification technology (the ``Destec Gasification Process''), is thought to be the cleanest coal fired power plant in the world. The project features an oxygen blown, slurry fed, two stage entrained flow gasifier, with heat recovery, dry filtration and a conventional amine based sulfur removal system to provide clean syngas to a GE 7FA based power generation block. The project has been in commercial operation since 1995 utilizing coal feedstock. This paper presents the results from testing of an alternate fuel, petroleum coke. Approximately 20,000 tons of a 5% sulfur petroleum coke was processed in the Wabash Plant with favorable performance and environmental results. Plant efficiency, emissions of SO{sub 2} and other air contaminants, trace metals balance, performance of the COS hydrolysis catalyst and sulfur removal system, are presented. Observations on plant operation, including slurry preparation, flux addition, ash deposition, and gas stream metallurgical testing, are discussed. Results indicate that future projects that utilize these alternate fuels could be implemented at a lower cost than Wabash by reduction in the size or elimination of some of the equipment. Dynegy believes this demonstration of the inherent fuel flexibility of its gasification technology will result in applications with other opportunity fuels, including coal fines, renewables, or waste materials.
