    摘要: In a method for growing ribbon-like crystal of crystalline substance, a seed crystal is contacted on the upper surface of melt of crystalline substance raised up to the level beyond the upper edge of a crucible, thereafter the contact interface between said seed crystal or a successively growing crystal and the melt (the solid-liquid interface) is cooled under freezing point of said crystalline substance, thereby the crystal is made to successively grow on said solid-liquid interface, while said seed crystal or said successively growing crystal is drawn out substantially in horizontal direction, wherein the circulating convection is made to cause in such a manner that high temperature melt flows underside of said solid-liquid interface, thereby the crystal growth in the direction of depth of the melt is prevented.

    摘要: An apparatus and a method for removing unburned carbon from fly ash capable of suppressing facility cost and stably conducting performance adjustment depending on property of the fly ash. The method comprises the steps of: adding water to fly ash to produce slurry; adding collector to the slurry, feeding the slurry and the collector to a static-type mixer 4, a venturi pipe 24 or the like to add shearing force to them; adding frother to them to generate air bubbles; and adhering unburned carbon of the fly ash to the air bubbles to raise the unburned carbon. The frother and air can be fed to the static-type mixer or the like together with the slurry and the collector. Depending on the change in property of the fly ash, the number of the static-type mixers or the like used in series can be increased or decreased, and depending on required capacity, the number of the static-type mixers or the like used in parallel may be increased or decreased. The static-type mixer may comprise a guide vane chamber 4b with plurality of guide vanes 4d for converting the slurry and the like, which are fed to the chamber, to spiral flow, and a current cutter chamber 4c with plurality of mushroom-shaped projections 4e for adding shearing force to the slurry and the like.

    摘要: Disclosed is a method for removal of an unburned carbon contained in a fly ash material. The method comprises the steps of adding water to the fly ash to prepare a fly ash slurry; shearing the fly ash slurry using an agitating blade that can rotate at a high speed to generate an active energy on the surface of an unburned carbon by the shearing force, thereby imparting lipophilicity to the unburned carbon; and adding a collecting agent and a foaming agent to the slurry containing the lipophylized unburned carbon to cause the attachment of the collecting agent to the lipophylized unburned carbon, and at the same time, causing the attachment of the unburned carbon having the collecting agent attached thereto an air bubble to separate the unburned carbon by flotation.
