METHOD FOR MEASURING CHLORINE CONCENTRATION IN SOLID FUEL, METHOD FOR PREPARING CALIBRATION CURVE, AND METHOD FOR MANUFACTURING FLUORESCENT X-RAY INTENSITY MEASURING SAMPLE

摘要

PROBLEM TO BE SOLVED: To provide a method for more simply, promptly and accurately than before measuring chlorine concentration in solid fuel, and to provide a method for preparing a calibration curve, and a method for manufacturing a fluorescent X-ray intensity measuring sample.SOLUTION: A method for measuring chlorine concentration in solid fuel, comprises: a measuring target sample preparation step of drying and pulverizing the solid fuel having unknown chlorine concentration and pressure-molding obtained granular pulverized material by a pressure device to prepare a measuring target sample; and a chlorine concentration measurement step of measuring chlorine concentration in the measuring target sample on the basis of fluorescent X-ray intensity obtained by measuring fluorescent X-ray intensity for the prepared measuring target sample and a calibration curve in which the fluorescent X-ray intensity is associated with the chlorine concentration in the solid fuel.SELECTED DRAWING: Figure 5
