Abstract
A method of estimating a surface tension of coal inert material includes determining in advance a first relational expression representing a relationship between a surface tension of coal inert material and a physical property value representing a coal rank; and measuring the physical property value representing the coal rank of a coal for which the surface tension of coal inert material is to be estimated, and calculating the surface tension of the coal inert material by using the measured physical property value representing the coal rank and the first relational expression.
