The Shawnee Power Station in western Kentucky consists of ten 150 MW units, eight of which burn low-sulfur eastern Kentucky and central West Virginia coal. The other units bum medium and high-sulfur coal in an AFBC unit and in a research unit. The eight low-sulfur coal units were sampled in a 1992 survey of Kentucky utilities. Little between-unit variation is seen in the ash-basis major oxide and minor element chemistry. The carbon content of the fly ashes varies from 5 to 25%. Similarly, the isotropic and anisotropic coke in the fly ash varies from 6 to 42% (volume basis). Much of the anisotropic coke is a thin-walled macroporous variety but there is a portion which is a thick-walled variety similar to a petroleum coke.
