Method for producing coal-water slurry, its system and slurry carrying mechanism

摘要

In a coal-water slurry production system, low grade coal is wet pulverized to a particle size of 3 mm or less to obtain pulverized coal slurry. The quality improvement treatment is performed on pulverized coal slurry under a pressurized hot water atmosphere of 300C or higher to produce a quality improved coal slurry. The quality improved coal slurry is dehydrated to produce quality improved coal cake and filtrate. The final coal-water slurry is produced from a quality improved coal cake. The filtrate is recycled to produce a pulverized coal slurry. A slurry transport mechanism is provided in the coal-water slurry production system to maintain stable transport of the quality improved coal slurry from the high pressure slurry vessel to the low pressure slurry vessel.
