Title: Fluidized bed combustion: A proven alternative
Abstract: Iowa is dependent on outside resources of coal, natural gas, and oil for fuel supply. Even though there are coal reserves within the state, high ash and high sulfur content have kept indigenous coal from wide use. With coal cleaning to enhance the quality, the Iowa coal industry still has not progressed appreciably. New and proven technology in the form of fluidized bed combustion (FBC) gives Iowa an opportunity to utilize native coal supplies in an economical and environmentally acceptable manner. In recent combustion tests sponsored by the Iowa Energy Policy Council, both Iowa coal and Iowa limestone were burned in a fluidized bed combustor. The results of these tests were conclusive. More than 90% of the sulfur dioxide was captured, efficiently, at its source in the combustor. Also, nitrogen oxide emissions were well below the most stringent environmental standards. The results of these tests are encouraging since they show a practical commercial alternative for meeting current and future environmental standards, for satisfying energy requirements with locally available coal in Iowa, and for supplying useful byproducts.
