Abstract
Coal-water mixture (CWM), a liquid fuel produced by mixing together coal and water with an aid of surfactant, has many advantages for storage and handling of coal and, moreover, for beneficiation of coal, transforming coal into a more appropriate form to handle and burn. Following the development of the coal-oil mixture (COM), a research program to develop a CWM technology has been made by Mitsubishi Heavy Industries, Ltd. for the past decade, covering the CWM production, transportation, storage and combustion.
This paper reviews an outline of the CWM research and it's results, specifically focusing on the handling process of two-CWM consisting of fine particles of coal and water.
