Abstract:
A method of operating a chamber coke oven having coking chambers and combustion chambers and vertically extending gas passageways at opposite longitudinal ends of each of the coking chambers between oven bricks and an inner surface of a door, the method comprising the steps of:charging coal which is adjusted to have a moisture content of not higher than about 6% into the coking chambers;holding the pressure in each of said coking chambers at a value at or about atmospheric pressure during an initial stage of coking;independently controlling the temperature at opposite longitudinal ends of each of said combustion chambers to within a predetermined range by supplying fuel gas and combustion gas to both longitudinal ends of each of the combustion chambers separately from a main burner for the respective combustion chamber to raise the temperature at both longitudinal ends of each of the coking chambers to accelerate carbonization of coke at both longitudinal ends of the oven; andsucking coking gas via said gas passageways.
