PROBLEM TO BE SOLVED: To provide a method for properly evaluating coal ash, capable of contributing to the quality control of coal ash.SOLUTION: The method for evaluating coal ash properties includes the steps of determining influence items that specify the density of coal ash, Blaine value, flow value ratio, and activity index of coal ash for expressing the density, the Blaine value, the flow value ratio and the activity index, as a tentative estimate equation containing a predetermined coefficient via the particle size, the ash composition, the concentration of unburnt combustible contents, and the ash content of coal ash from the known actual measurement data, determining each of the coefficients; forming the tentatively estimated equation for estimating the density, the Blaine value, the flow value ratio, and the activity index, based on the particle size, the ash composition, the concentration of unburnt combustible contents, and the ash content of coal ash; and evaluating the properties of coal ash to be targeted. |
