Abstract

A method and apparatus that deterioration of the flow state of a coal/kerosene slurry while preventing the damage caused by overloading to thereby achieve excellent solid-liquid separation performance. In a solid-liquid separation supplying a dehydrated coal/kerosene slurry to a decanter-type centrifugal separator to separate the coal/kerosene slurry into a solid fraction and a liquid fraction, an opening degree target value is determined on the basis of the difference between a target value and an actually measured value of a torque that acts on a screw conveyor of the decanter-type centrifugal separator, and the opening degree of a flow volume control valve, which is arranged in the middle of a supply line for supplying the coal/kerosene slurry into the decanter-type centrifugal separator, is adjusted to the opening degree target value.
