PROBLEM TO BE SOLVED: To make it possible to secure improvement of production capacity of coke in a coke oven. SOLUTION: A range finder 3 to noncontactly measure the distance to the upper surface of coal is installed at the leading end of a probe 1 of a levelling apparatus for levelling the upper surface of coal charged in a carbonization chamber of the coke oven. The probe 1 is inserted into the carbonization chamber after coal is charged to measure the upper surface of coal in the carbonization chamber using the range finder 3. The amount of coal for filling the space (S) between the prove 1 and the upper surface of coal is calculated on the basis of the shape of the carbonization chamber and the results of the measurement. The coal in an amount thus calculated is additionally charged. COPYRIGHT: (C)2005,JPO&NCIPI |
