Document Type and Number:
Japanese Patent JP2017023895
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a coal ash management method for solving occurrence of various problems from view points of quality and production in the case where the coal ash is used as a raw material for Portland cement clinker or CaO AlO2SiOcontaining clinker, under such the situation that the chemical compositions of a coal ash produced from a coal-fired power plant are greatly different depending on the kinds, product classes and discharge sources of the coal used as a fuel.SOLUTION: As to the fuel of coal and the like used in a coal-fired power plant, the chemical compositions of the residues after ignitions of 850 ± 50°C are analyzed respectively, and usefulness and application of the coal ash produced from the power plant or the like are determined on the basis of the analysis value.SELECTED DRAWING: None
