Abstract The application of microwaves has a demonstrated potential for the ultimate removal of water from fine coal. The electromagnetic energy absorption in coal during microwave drying is controlled by several factors, with dielectric properties being among the most important. In this paper, the measured dielectric properties of various ranks of coal are presented as a function of frequency and moisture content. A knowledge of the dielectric properties is essential in estimating the electromagnetic energy absorption in coal during microwave heating. Key Words: Dielectric constant, Dielectric loss, Coal, Coal rank, Coaxial airline.
