    The coal is dry to the touch and the 10% moisture is inherent moisture moisture that will not be removed by air-drying or by being stored on a sunny summer day on the coal pile. Inherent moisture is basically liquid phase water that is bound within the coal. It will not be released until the coal is pulverized and/or exposed to high temperatures in a low humidity environment, which is essentially what is done in a coal pulverizer.
