Japanese Patent JP2022041973
Kind Code:
A
Abstract:
To provide a device, a power generation plant, a method for controlling the device, a program, a power generation plant system and a method for controlling the power generation plant system which can more accurately determine whether an abnormality occurs in a grinding machine.SOLUTION: This device comprises: a determination unit 51 which, when a differential pressure between a grinding machine that grinds a supplied solid fuel, and a furnace of a boiler which burns the ground solid fuel exceeds a first threshold, determines that an abnormality occurs in the grinding machine, the differential pressure being detected by a differential pressure detection unit 102; and a first threshold setting unit 52 which sets the first threshold to be used by the determination unit 51, where the first threshold setting unit 52 sets the first threshold on the basis of the amount of the solid fuel supplied to the grinding machine and/or a primary air flow rate supplied to the grinding machine, and at least one among the temperature of primary air discharged from the grinding machine, moisture content of the solid fuel supplied to a mill, and the fineness of the solid fuel discharged from the grinding machine.SELECTED DRAWING: Figure 2
