Abstract

Procédé de préparation de mélanges charbon-eau renfermant 60 à 85 % de charbon, 15 à 40 % d'eau et au moins un additif caractérisé en ce que l'on ajoute progressivement pendant le broyage la quantité d'additif correspondant à la surface spécifique disponible. Ce procédé rend disponible le charbon sous la forme d'un liquide pompable, facile à transporter et donc pour une utilisation aisée en tant que combustible.Process for the preparation of coal-water mixtures containing 60 to 85% of coal, 15 to 40% of water and at least one additive, characterized in that the quantity of additive corresponding to the specific surface is gradually added during grinding available. This process makes the coal available in the form of a pumpable liquid, easy to transport and therefore for easy use as fuel.
