€IE behavior of a coal auh during the combustion of a coal in a furnace is important @ T in the evaluation of that coal as fuel. Our knowledga of the behavior of coal ash is still largely empirical, in spite of recent progress, and, until more is known about the manner of occurrence and distribution of the ash-forming Ioineral matter in the coal and the relationships between ash composition and thermal behaviors, attempts to improve the characteristics of coal ashes will have to remain on an empirical cut-and-try basis. There is a growing trend toward extensive preparation of coal. It would be highly desirable if the ash characteristics of certain coals could be greatly improved by preparation. It is with that in mind that the studies here reported were undertaken. Among the more important plmses of the coal ash problem are the relstionships between ash composition and ash-softening temperature, between ash-softening demperature and tendency to clinker, and between the distribution and occurrence of mineral matter in the coal and the tendency of the ash to form clinkers. This report is to be considkred as a preliminary survey to a more detailed study of certain phases of the problem. Coal Mineral MatterExamination of numerous coal ash analyses, calculated to a sulfur-triodde-free basis indicates that over 95 per cent of coal ash is composed of alumina, silica, ferric oxide, lime, and magnesia. The magnesia content is frequently hegligible. The remaining 5 per cent includes such items as sodium Responaibie for the portion of the paper d a t i n g to the charaater and oonstitution of coal mineral matter.
