Abstract

An apparatus for preparing coal water slurry comprises a first unit for providing crude coal water slurry, a second unit for providing fine coal water slurry, a third unit for providing dry crude coal particles, a mixing unit for mixing coarse coal water slurry, fine coal water slurry and dry coarse coal particles. The invention also relates to a related method.

Description

technical field [0001] The invention relates to a device and a method for preparing coal water slurry. Background technique [0002] Coal water slurry is currently widely used in the gasification industry. Generally, the higher the concentration of coal in the CWS with an acceptable viscosity, the more desirable. However, currently available devices and methods do not provide satisfactory coal water slurries, especially when low rank coals are used as raw materials. [0003] Therefore, new and improved devices and methods are needed to prepare coal water slurry. Contents of the invention [0004] The purpose of the present invention is to provide a new and improved device and method for preparing coal-water slurry. [0005] In one aspect, the present invention relates to a device for preparing coal water slurry, which comprises: a first unit for providing coarse coal water slurry; a second unit for providing fine coal water slurry; for providing dry coarse coal particle...
