Quality design is one of the important tasks for new developing coalmines in order to satisfy the market needs in Japan. However, quality control involving the practical evaluation of actual boiler properties is not carried out at coalmines. Therefore, unexpected troubles often take place during coal handling and combustion at coal users.<BR>The purpose of this study is to establish the coal quality design and quality control system that predict the actual boiler performances and feedback their results to coal production management. This study was carried out in step with a development schedule of Xuchang coalmine in Shandong province, China. Prediction of boiler performance based on the properties of test production sample, evaluation by pilot plant test, optimization of preparation process, establishment of quality control system and verification by actual boiler test at user were described.
