APPARATUS FOR MEASURING THE AMOUNT OF ADHESIVE COAL OF BLENDING BIN

A method for measuring amount of an adhesive coal of a blending bin is provided to check the amount of an adhesive coal and control the inlet amount and discharged amount of the coal by sensing upper and lower limit positions where the coal is stored and calculating a difference value between accumulation values of the inlet amount and discharged amount of the coal. A method for measuring amount of an adhesive coal of a blending bin comprises the steps of: sensing a lower limit position in which the coal is stored in the blending bin(S11); accumulating the inlet amount and discharged amount of the coal(S13); sensing an upper limit position in which the coal is stored(S14); measuring the upper limit inventory amount of the coal(S15); and subtracting a difference between the inlet amount and the discharged amount of the coal(S16). An accumulated amount of the coal, which is in less than the lower limit position, is more subtracted(S12).
