  • Coal Drying Improves Performance and Reduces Emissions

    The combination of all these effects caused by firing drier coal will result in an improvement in boiler efficiency and unit heat rate, primarily due to the lower stack loss and lower station service power. In some cases this performance improvement will also allow higher power output with existing equipment.
