Thompson, B R

A plurality of sole flue-heated, non-recovery coke ovens constructed in side-by-side relation in a battery have their chimney uptake outlets connected to a common combustion tunnel extending longitudinally of and above the battery and connected to stacks at spaced intervals along its length. Each oven has a bypass flue directly connecting the top of its coking chamber to the combustion tunnel, and a normally closed valve in each bypass is operable to selectively connect the coking chamber to the tunnel to permit charging gases to be drawn from the chambers to be burned in the tunnel and stack. The bypass valve is closed during coking so that the partially burned gases from the crown of the coking chambers are led through downcomers in the oven walls to the sole flues where a controlled amount of combustion air can be admitted to promote the continued burning process and provide maximum heat in the sole flues. The gases then pass through the chimney uptakes to the tunnel where additional combustion air can be admitted to assure complete combustion in the tunnel and stack before being discharged to the atmosphere. Combustion air admitted into the sole flues can be preheated in pipes extending through the base slab beneath the sole flues where waste heat is extracted to protect the foundation of the ovens while increasing the temperature in the sole flues.
