Abstract (en)
[origin: WO2006113176A2] A method and apparatus is provided for conveying lime slurry, removing and controlling the amount of grit, and feeding lime slurry, wherein the lime slurry moves through a recirculation loop, and wherein gravity removal of grit from the lime slurry takes place. A stilling well is provided, inside or outside the slurry tank, either fixed in cross-sectional area or adjustable, but wherein the cross-sectional area of the stilling tank can be selected or adjusted to alter the flow velocity of slurry therethrough and the residence time of slurry therethrough, as slurry is delivered through the stilling well via a suction line located therein, whereby grit can be separated via gravity from slurry in the slurry tank prior to withdrawal of slurry through the stilling well.
