ABSTRACT:
A single regenerative coke oven battery is constructed and operated as a plurality of individual and separate groups of heating walls, each group capable of independent reversal and heating cycles. During slow-down operations, one or more of the individual groups of heating walls is shut down for a preselected time period, with no flow of combustion air, fuel and waste gas in the heating walls, while the remainder of the groups are operated at substantially full air and gas flow. The battery is capable of a slow-down operation while avoiding uneven coking and variations in the amount of byproduct coke oven fuel gas generated.
