Abstract

PURPOSE: To reduce transportation cost and to enable the use of coal in wide fields, by liquefying partially coal at a place of coal production, etc., transporting directly slurry of mixed solid and liquid coal ingredients and feeding the slurry to a combustor, etc.
CONSTITUTION: The coal 1 is ground into a necessary particle diameter and the particle sizes are adjusted by the pretreating device 2. The prepared liquefied oil 7 of coal is partially recycled to give slurry of a raw material for liquefaction consisting of coal and the liquefied oil of coal. The slurry is passed through the pressure device 3 of high pressure for slurry and slurry comprising oil, heavy tar, char, and ash is formed by the liquefying device 4. The coal 11 is additionally added to the slurry so that the slurry is adjusted to a slurry concentration of the upper limit of transportation, the slurry is transported by sea 13, etc. and fed to the device 15 to use it. The slurry formed by the device 4 is partially subjected to the solid-liquid separator 6 and the liquid material is separated and returned to the device 2 as the recycling oil 7.
