Waste heat exhaust system for side burner regenerative coke oven batteries having a divided heating system

摘要

A waste heat exhaust system for side burner regenerative coke oven batteries, comprises a coke oven battery which has a chimney flue connected to one end of the battery and includes a plurality of flue gas ducts which extend in a longitudinal direction and are connected at their one ends to the chimney flue. A plurality of transverse first flues of unequal length have outer ends which are connected to respective waste gas lines which are located on the pusher side of the battery. The first flues extend transversely to the flue gas ducts and they are connected at their inner ends to respective ones of the gas ducts. A similar set of second flues of unequal length have outer ends which are connected to the waste gas lines on the coke side of the battery and they have inner ends which are connected to respective ones of the gas ducts. In the preferred arrangement, three of the first flues are connected to waste gas lines on the pusher side and terminate at their inner ends on one side of the gas ducts and three of the second flues are connected to waste gas lines on the coke side terminating at their inner ends on the opposite side of the wall of the associated gas duct.
