Abstract
This report describes the occurrence of spontaneous heating in an 800-metric-ton heap of Wyoming coal. The major part of the report deals with the oxidation of Pittsburgh seam and Wyoming subbituminous coal and describes an experiment in which 1 metric ton of Wyoming coal is stored in a 5-meter-long insulated container while air is passed through. Temperature rises, rates of oxygen absorption, and gas compositions of the air stream are measured. The report relates the results of the experiments to a theory of spontaneous heating, which stresses the importance of the moisture content of coal and the relationship between the heat necessary to evaporate water to the heat available from coal oxidation.
