Abstract: | Existing methods for estimating the storageability of fuel in open coal depots are analyzed. It is inferred that the capacity of coals for oxidation and spontaneous combustion cannot be unambiguously associated with the name of the coal basin, deposit, or grade. Methods for calculating a generalized parameter reflecting a fuel group are suggested. It is shown that the explosiveness factor Kf of solid fuels calculated from the data on technical and elemental compositions can be used as a generalized characteristic for classifying fuels according to their resistance to oxidation and spontaneous combustion. |
