  • Drying Coal by Microwave

    It has been established that coal is a poor absorber of microwave energy and water is a good absorber. Unlike the current methods of drying fine coal, which heat both the coal and the water, this research demonstrates a method to heat and drive off only the water. This method is more energy efficient and will minimize the generation of fugitive ...
