The dilatation of coal under homogenous heating by microwave heater was investigated. The experimental apparatus consisted of the microwave heater and the detector of coal dilatation. Sample coal was heated at the rate of 3K/min up to 550℃ and the change of coal height was measured by laser range meter. The difference between preset temperature and coal temperature was within 5℃, so it was confirmed that the power control of microwave was no problem. The dilatation measured by this method differed from TD measured by dilatometer. Especially, the dilatation of high fluidity coal was given lower dilatation than that estimated from TD value.
