Abstract：Microwave heating is used to research the moisture content and temperature rising characteristics of fine coal under the laboratory condition. The influenced factors of the dewatering effects during microwave heating are investigated, which are initial moisture content、microwave output power、particle size and sample weight. The results show that fine coal was effectively dewatered by microwave heating, and the primary influential factor is microwave output power. With increasing irradiation time, the dewatering efficiency of sample with different factors tends to be same. The temperature rising characteristics of fine coal dewatering by microwave heating could be divided into three periods: temperature rising fast firstly; secondly, appeared 100℃ constant temperature platform and moisture content reduced rapidly; thirdly, temperature rising slowly while most of moisture was removed.
