METHOD OF CHARGING FEED COAL INTO COKE OVEN

摘要

PROBLEM TO BE SOLVED: To provide a method of charging feed coal into a coke oven which enables an effective decrease of scattering of coke intensity in a carbonization chamber, only taking into consideration the method of filling a compounding coal into a hopper group loaded in charging car and the method of charging the compounding coal into the carbonization chamber. SOLUTION: This method of charging feed coal unto the coke oven comprises filling (i) low intensity compounding coal B into a hopper at a central part of the charging car and high intensity compounding coal A into hoppers at an extruder side and an outlet side, or (ii) the coal B at lower portion of the hopper at the central part and the coal A at upper portion of the hopper at the central part ad into the hoppers at the extruder side and the outlet side. And by open-close timing of the hoppers in the charging car and/or controlling a rate of charging the compounding coal into the carbonization chamber from the hoppers, charging (I) the coal B at a central part of a oven longitudinal direction in the chamber and the coal A at the both end sides of the oven longitudinal direction, or (II) the coal B at a lower portion side of the central part of the oven longitudinal direction in the chamber and the coal A at an upper portion side of the central part of the oven longitudinal direction and at the both end sides of the oven longitudinal direction.
