The influence of microwave irradiation and ultrasonic vibration on granularity of 0.074mm pulverized coal was investigated in this research. It is indicated in the results that the granularity of coal decreased after microwave treatment, which led to the increased in specific area of pulverized coal in combustion reaction and consequently optimized the kinetic condition of combustion reaction. The specific area of pulverized coal gradually increased with the extension of irradiation time under 132W and 264W microwave powers and simultaneously the pulverization of pulverized coal was more significant under 264W microwave power. The same effect was also found in ultrasonic treatment while the granularity of pulverized coal decreased more seriously under higher powers.
