Abstract:
A control device for the coal pulverizing apparatus includes a first command value generation part for generating a command value of a first parameter including at least one of rotational speed of the table, pressing force of the roller to the table, or air supply amount in the air supply part, and a second command value generation part for generating a command value of a second parameter including a rotational speed of the rotary classifier. The first command value generation part is configured to determine the command value of the first parameter, based on a first preceding signal determined in accordance with at least load information of a combustion device which burns the pulverized coal from the coal pulverizing apparatus. The second command value generation part determines the command value of the second parameter, based on a second preceding signal determined in accordance with at least the load information.
