    摘要: An apparatus for controlling the injection quantity of pulverized coal by measuring the flow rate of the pulverized coal in a conveying pipe, through which the pulverized coal is injected into tuyeres of a blast furnace, in order to regulate the opening of a valve installed between a feed tank and the conveying pipe based on the measured flow rate, and also by regulating the internal pressure of the feed tank so as to maintain the difference in the internal pressure between the feed tank and the conveying pipe within a predetermined range. The thus configured apparatus provides rapid-response and high-accuracy in control, wide-range controllability, and allows to control the injection quantity of the pulverized coal even when supplying the pulverized coal to the feed tank.
