ABSTRACT:
A sole flue nonrecovery coking oven battery includes a plurality of elongated coking ovens constructed in side-by-side relation with common sidewalls downcomers connecting the ovens through the sidewalls to the sole flues, uptakes connecting the sole flues through the sidewalls to an elongated tunnel extending transversely of the battery and a single stack connected to the elongated tunnel applying a draft to all ovens in the battery through the downcomers, sole flues and uptakes, and an improved draft control system includes an adjustable draft regulating valve for controlling the flow of gas from the uptakes beneath each oven to the common tunnel. An adjustable damper type stack draft valve is also provided for opening and closing the stack to vary the draft applied to the stack to the battery.
