Ash with low melting point causes the generation of large mass of clinker and a lot of operational problems in pulverized coal combustion boilers. Therefore, the development of the practicable technology in order to evaluate and predict the generation of large mass of clinker is demanded. In this study, the analysis of clinker samples and the evaluation of the operational results are conducted. As a result, it is clarified that the molten slag fraction in ash obtained by the chemical equilibrium calculation and the content of iron in ash affect the generation of large mass of clinker. Moreover, it is confirmed that this evaluation method is one of the useful indices for proper coal blending to reduce the generation of large mass of clinker.
