Abstract
A method of regulating fuel for a coke oven by a programmed heating method in which a change of the fuel supply rate contains at least one substantial reduction during the coal carbonization process in the coke oven, wherein the improvement comprises setting up a standard curve for the ethylene concentration or the tar concentration based on the operating conditions of the coke oven and the conditions of feed coal, measuring the ethylene concentration or the tar concentration in the coke oven gas generated in the carbonization chamber, and controlling the fuel supply rate so as to minimize the difference between the measured value and the standard value.
