我厂反射炉生精矿熔炼是采用粉煤作燃料,七个燃烧喷嘴的粉煤由七台螺旋给煤机供给。燃烧粉煤的数量是影响反射炉技术经济指标的重要因素之一,燃煤供给量多了,浪费燃料,严重时会造成炉头积煤;燃煤数量不足,也直接影响炉内温度。为了准确计量粉煤供给量,保证反射炉熔炼作业的进行, Refined furnace concentrate refineries mine is the use of pulverized coal as fuel, seven burning nozzle pulverized coal supplied by seven spiral feeder. The quantity of burning pulverized coal is one of the important factors that affect the technical and economic indexes of reverberatory furnace. The quantity of coal supplied is too much and the fuel is wasted. In severe cases, it will cause the coals to accumulate. When the quantity of coal is insufficient, it also directly affects the temperature in the furnace. In order to accurately measure the supply of pulverized coal to ensure that the refiner furnace smelting operation,
