Used to bleed (burn) excess coke oven gas when the gas holder is full, and the ovens are generating more gas than can be used in the facility. Sometimes also called a “waste stack.”
Use Evergreen 1/2″ tubing to complete stack itself, then add Tichy Caged Ladders (P#8002) to complete. Comes with adapter for 1/2″ down comer pipe from Coke Battery. As well as auxiliary pipe bosses near base.
