Moist, mineral matter-free gross calorific value

Such data are necessary for calculation of parameters in the classification of coal by rank dry, mineral-matter-free volatile matter (or fixed carbon) as well as moist, mineral-matter-free gross calorific value. For volatile matter and fixed-carbon data, it is also necessary to assume that 50% by weight of the sulfur is volatilized in the volatile matter test and therefore should not be included as part of the organic volatile matter (nor should the loss from clays and carbonate minerals) ... 

Fixed carbon limits (dry, mineral-matter-free basis), % Volatile matter limits (dry, mineral-matter-free basis), % Gross calorific value limits (moist, mineral-matter-free basis) ... 

High-volatile A bituminous coal rank of coal such that on a dry, mineral-matter-free basis, the volatile matter content of coal is greater than 31% (or the fixed carbon content is less than 69%), and its gross calorific value is equal to or greater than 14,000 Btu/lb of coal on a moist, mineral-matter-free basis, and the coal is commonly agglomerating.
