In this paper, influences of temperature and moisture on the flowability of granular coal are experimentally examined. Stirring torque required to an impeller rotating in the bed of coal and rate of gravitational flow of the coal are used as criterions of the flowability and the following results are obtained:
(1) At the temperature of 100°C and 400°C, the coal showed a special feature of fluidity.
(2) As the moisture content increased about 2-3% beyond the internal moisture of the coal, the gravity flow rate decreased rapidly to a choking state.
