Abstract: Pulverized coal feed tanks are emptied in sequence via a transport line into the hot blast of a blast furnace. Each tank is carried by three load cells whose outputs are summed and differentiated to obtain the actual feed rate. Gas pressure in the tank is controlled in dependence on the actual feed rate so as to achieve a desired feed rate.

The load cells may be duplicated in series, and the summed outputs of the two sets of load cells compared to detect malfunctioning of a load cell, again resulting in cessation of feeding from that tank.
