Reconversion to Coal Firing at Crystal River

Units 1 and 2 at the Crystal River Plant of Florida Power Corporation were originally designed for coal firing in the 1960's, were converted to heavy fuel oil firing in the early 1970's when oil was readily available and economically priced, and subsequently were reconverted to coal firing by 1980 when coal firing again became more favorable. This paper describes the plant modifications and additional construction required for the reconversions of both units. Specifically described are the boiler modifications, ash handling system modifications, precipitator and associated ductwork and induced draft fan additions, coal handling system modifications, and foundation and superstructure designs.
