Coal Handling Problems Solved at Jenike &

Little consideration was given during the design stage to the flow properties of the coal. As a result, flow problems could be expected, even when handling what is considered to be relatively free-flowing bituminous coal. After switching to a low sulfur sub-bituminous coal, NSP experienced several fires and one explosion in its unit 7 coal bunker.
