Maintenance is the cheapest way to improve fine coal dewatering
Abstract
There are a great many things that a preparation plant operator can do right now to increase fine coal dewatering effectiveness and maintenance is one of them, says Donald A. Dahlstrom, at the University of Utah. Dewatering of fine coal is increasingly important, because electricity generation, the largest coal consumer, is so strongly affected by the moisture content. Every pound of water put into a boiler raises costs about 2 1/2 cents. The heat it takes to turn water to steam and get it out the stack is heat that could have been used to generate power. In addition, there is the cost of shipping the water. You can add the freight costs to that. In contrast it costs about 1/2-cent/lb to remove the water at the preparation plant.
