Abstract
PURPOSE: To prepare coal and heavy oil-containing slurry having a constant viscosity and stable properties, by controlling the concentration of coal and the temperature of heavy oil being fed.
CONSTITUTION: Coal C fed via a conveyor 2 and heavy oil L fed via a heater 7 are mixed in a wet ball mill 3 to provide coal and heavy oil-containing slurry. In this process, coal C is fed in a constant amount by the controlled conveyor 2. A coal weight detection signal from a transducer 12 is compared with a signal from a heavy oil flow meter 5 in a measuring instrument 16 for ratio for controlling heavy oil, and a valve 6 is controlled by the resulting output signal to control the flow amount of heavy oil L. Thus, the concentration of the coal and heavy oil-containing slurry in the mill 3 is maintained at a desired value. On the other hand, a heavy oil-temperature signal detected on the way from the heater 7 to the mill 3 is compared with a set temperature signal from a setting device 19 in a controller 20, and a flow control valve 22 for steam sent to the heater 7 is controlled by the resulting output signal to control the heating of heavy oil L. Thus, the temperature of heavy oil fed to the mill 3 is maintained at a desired value.
