Abstract

PURPOSE: To determine a suitable blending ratio of grades of material coals, by calculating a cold strength after carbonization and (strength after reaction) according to the inert content and an average vitrinite reflectance of respective material coals measured as parameters.
CONSTITUTION: For example, the inert contents in material coal of respective grades are measured by qualitative analysis of composition, and the relation between the inert content I(%) and strength after reaction by reactive test CRS(%) is given in groups of an average vitrinite reflectance R0(%) of respective grades of the material coal. The inert content and the average reflectance measured of the material are plotted as a mark X. Other curves in the fig. 2 parallel to the curves in the fig. 1 corresponding to the reflectance (R0: 0.7 to 1.4) of the material coal of respective grades are drawn in such a way that the other curves pass through the mark X. The average inert content of blended coal is given from a weighed mean. For example, the straight line A is drawn under a condition that the average inert content is 28 wt.%, the intersections of the straight line A and the curves correspond to strength after reaction. The material coal of respective grades is blended according to this value.
