Coal Drying Improves Performance and Reduces Emissions

Coal Drying Improves Performance and Reduces Emissions

power plant, less coal needs to be fired. This reduces the burden on the coal handling system, conveyers and crushers. Also, since dryer coal is easier to convey, this reduces maintenance costs and increases availability of the coal handling system. Crushed coal is fed into the bunkers from where it flows by gravity to the coal feeders.
