Filed: 1994-03-29
Abstract: PURPOSE:To provide a method for keeping the temperature of a regeneration chamber within a range not to generate the crack on the partition wall of the regeneration chamber even by lowering the operation rate of a coke oven. CONSTITUTION:An end part of a regeneration chamber 3 is heated by introducing a hot combustion gas through a blowing nozzle 22 penetrating through the furnace wall 4 into an end of a regeneration chamber 3 acting as a pull- down part by the switching of combustion operation. Since the heating rate of the end part of the regeneration chamber 3 is increased by this process, the temperature of the partition wall of the regeneration chamber 3 can be maintained within a prescribed range even if the heating rate of the end part of the regeneration chamber 3 with the combustion gas flowed from a combustion chamber 2 is decreased by the closure or narrowing of the combustion gas flow channel connecting the combustion chamber 2 with the regeneration chamber 3. Accordingly, the operation rate of the coke oven can remarkably be lowered.
