Title:
固体燃料粉砕システム、固体燃料粉砕装置および固体燃料粉砕システムの制御方法
Document Type and Number:
Japanese Patent JP6999349
Kind Code:
B2
Abstract:
The invention provides a solid fuel crushing system and a control method thereof, and a solid fuel crushing apparatus. The frequency of stopping any one of the plurality of solid fuel crushing apparatuses is reduced by reducing the lower limit value of the operation load for stably operating the crushing apparatuses. The solid fuel crushing system includes a generation unit that generates a control command based on a target load of a boiler; a determination unit that determines whether or not the operation load of the solid fuel crushing device operated on the basis of the control command is lower than a predetermined lower limit value; and a transmission unit configured to transmit control commands, when the operating load is not lower than the predetermined lower limit value, respectively to the plurality of solid fuel crushing apparatuses. When the operating load is lower than a predetermined lower limit value, the transmission unit transmits a stop command for stopping the operation to at least one of the plurality of solid fuel crushing apparatuses, and the solid fuel crushing apparatus has a control unit for controlling the rotational speed of a crushing table on the basis ofthe control command transmitted from the transmission unit.
