Abstract
There is provided a control device of a coal pulverizer which enables estimation of a coal output with a precision suited for a purpose. In a control device of a coal pulverizer which pulverizes coal by the coal pulverizer and estimates coal output by which the pulverized coal is output to a boiler, the control device includes a main operation circuit which calculates a command signal associated with a coal feed rate on the basis of detection data from a boiler or a power generator connected to the boiler, and an additional control unit which calculates the deviation between a standard coal output pattern preset in the coal pulverizer, and a current coal output pattern, and adds a calculation result by the additional control unit to the main operation circuit as a correction signal.
