In the injection of pulverized coal into a blast furnace,there are some factors which affect the readout of electronic-weighing system.Through analyzing the measuring errors,it is found that the main reasons are pressure fluctuations of storage tank and puffing tank.According to the interaction of pressures,a neural-network-based method combined with fuzzy logic is adopted to enhance the precision.Experimental results show this method is satisfactory.
