Title:
METHOD FOR DEWATERING WATER-CONTAINING COMBUSTIBLE SOLID
Document Type and Number:
WIPO Patent Application WO/2006/030510
Kind Code:
A1
Abstract:
A method for dewatering a water-containing combustible solid, which comprises heating a water-containing combustible solid (exclusive of coal) to a temperature of 100 to 300&ring C under a pressure of the saturated water vapor pressure at the heating temperature or higher in a sealed vessel and simultaneously applying a shearing force of 0.01 to 20 MPa to the water-containing combustible solid. The above method allows the production of a mixture (water slurry) which contains the water separated from the water-containing combustible solid and a combustible solid being removed of water, has a suitable viscosity and water content, and can be subjected to spray combustion, at a low cost.
