Applicability of Coke Plant Control Technologies to Coal

Although coke production from each oven is basically a batch process a coke oven plant is operated such that the battery of ovens con- tinuously produce coke oven gas and byproduct chemicals. In the Byproduct coke oven process coking is accomplished at temperatures of 1 090 to 1 150°C and atmospheric pressure for a period of 16 to 27 hours.
