Abstract: PURPOSE:To rapidly reduce a feed coal quantity without undershooting for a rapidly reducing operation by making the primary lag time constant of the feed coal quantity variable in accordance with time. CONSTITUTION:The quantity of coal fed from a coal feeder controller 12 enters a primary lag 8 A primary lag time constant is fixed at a constant value by a signal generator 10 during an ordinary operation, but when a first cutback (FCB)/runback is operated, the primary lag time constant becomes variable in synchronism with the time by a function generator 11. When the primary lag time constant 18 is made gradually short before a fuel instruction 21 reaches a desired value, a feed coal quantity 20 is reduced after the primary lag, and a fuel deviation becomes small. According to this arrangement, a feed coal quantity 19 prior to the primary lag becomes small in undershooting. After the fuel instruction 21 reaches the desired value, the primary lag time constant is made long on the contrary. According to this arrangement, variations after the primary lag become small, and as a result, the feed coal quantity 19 prior to the primary lag gradually approaches to the desired value so as to enable said quantity 19 to be brought into a required feed coal quantity which meets a rapid reduction without undershooting.
