Research on fat coal quality difference

The comparisons of fat coal from Shandong Province, Shanxi Province, Anhui Province through proximate analysis, plastometric indices, Gieseler fluidity, Arnu-Audibert´s dilatometer, coke optical texture of single coal are studied. It´s pointed out that it´s not enough just by proximate analysis, plastometric indices to evaluate fat coal quality. They are quite different in the aspects of Gieseler fluidity, Arnu-Audibert´s dilatometer, coke optical texture of single coal and every index of fat coal should be analyzed synthetically.
