Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control device for a coal pulverizing apparatus, the coal pulverizing apparatus including a rotatable table, a roller configured to pulverize a coal supplied from the table, a rotary classifier configured to classify a pulverized coal obtained by pulverizing the coal with the roller, and an air supply part configured to generate an air flow for guiding the pulverized coal toward the rotary classifier, the control device comprising: a first command va…
