METHOD OF PRODUCING COAL-WATER SLURRY AND INSTALLATION FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC C10L1/00 C10L1/32 

FIELD: chemistry.

SUBSTANCE: invention discloses a method of producing a coal-water slurry comprising a water-coal slurry capable of being used at power plants, characterized in that the water-coal slurry is produced by electrically and thermally activating fine coal particles in the slurry by an electric discharge throughout the container volume, with the possibility of achieving aggregative and sedimentation stability of the slurry in the processing period, in the entire volume of the container, an electric discharge is produced between the rotating electrode, which serves as a cathode, and the inner surface of the vessel body, which serves as an anode, while the total volume of the container receives a specific energy consumption of 0.4 to 0.6 kW*h/kg at a temperature of 273 to 393 K by electrothermal current on the coal particles in the slurry, with the emission of gases CH₄, H₂ and CO and with the possibility of intensifying the process of incineration of the slurry on the energy objects, resulting in the formation of filamentary channels of electrical discharge between the electrode and the vessel body that pass through the surface of the coal particles and through the ionized water, wherein the distribution area of the channels is moved along with the rotation of the electrode. An installation of producing a coal-water slurry is also disclosed, which comprises a container with a slurry made in the form of a steel container, an electrode that is made of spherical steel and mounted inside the container with a rotation capability and fixed to the axis of an electric motor connected to a laboratory autotransformer, while all parts of the installation are located inside the steel frame.

EFFECT: producing a sedimentally stable water-coal slurry at low energy costs with maximum energy efficiency and without the use of chemical agents.
