Abstract
The present technology is generally directed to systems and methods of controlling or reducing the output rate of a coke oven through gas sharing providing an extended process cycle. In some embodiments, a method of gas sharing between coke ovens to decrease a coke production rate includes operating a plurality of coke ovens to produce coke and heated exhaust gases. In some embodiments, a first coke oven is offset in operation cycle from a second coke oven. The method further includes directing the heated exhaust gases from the first coke oven to the second coke oven while the second coke oven is mid-cycle. The heat transfer allows the second coke oven to extend its cycle while staying above a critical operating temperature. By extending the operational cycle while generally maintaining output per cycle, overall production is decreased.
