Carbonizing Properties: Pocahontas Number 6, Davy Sewell, and Fire Creek Coals from West Virginia and Upper and Lower Kittanning and Upper and Lower Freeport Coals from Pennsylvania
From Forward: "The value of this survey of the carbonizing properties of American coals by a standard method lies in the comparability of the results on different coals. It must recognized that no standard laboratory method of carbonization, even on a large unit, can yield results that exactly duplicate those obtained in ovens and retorts. The commercial results vary with the type of oven or retort. Allowance must be made for such differences in interpreting the BM-AGA test results in terms of commercial plants."
