Abstract
The present technology is generally directed to non-perpendicular connections between coke oven uptakes and a hot common tunnel, and associated systems and methods. In some embodiments, a coking system includes a coke oven and an uptake duct in fluid communication with the coke oven. The uptake duct has an uptake flow vector of exhaust gas from the coke oven. The system also includes a common tunnel in fluid communication with the uptake duct. The common tunnel has a common flow vector and can be configured to transfer the exhaust gas to a venting system. The uptake flow vector and common flow vector can meet at a non-perpendicular interface to improve mixing between the flow vectors and reduce draft loss in the common tunnel.
