METHOD FOR ESTIMATING VITRIFICATION RATE OF COAL ASH
PROBLEM TO BE SOLVED: To provide a method for simply and further accurately estimating a vitrification rate of coal ash which is suitable for automation.SOLUTION: The method for estimating a vitrification rate of a coal ash sample includes the steps of: (A) obtaining a first estimation value of the vitrification rate of the coal ash sample using the PONKCS method; (B) calculating the total amount (x') of SiOand AlOcontained in the coal ash sample, and an ignition loss of the coal ash sample; and (C) obtaining a second estimation value by subtracting a correction amount (y'), corresponding to the total amount (x') obtained in the step (B), from the first estimation value obtained in the step (A), on the basis of y=ax+b (where a and b each represent a constant), which is a relational expression of the total amount (x) of SiO, AlOand an ignition loss, determined by using a plurality of types of coal ash, and a correction amount (y) represented as (z-z'), which is a difference between a vitrification rate (z) calculated using the PONKCS method and a vitrification rate (z') calculated using an internal standard method.SELECTED DRAWING: Figure 3
