COKE OVEN EMISSION CONTROL METHOD AND APPARATUS ABSTRACT OF THE DISCLOSURE A method of and apparatus for controlling emissions from nonrecovery coke ovens in which hot partially burned distillation products are discharged from a plurality of such ovens constructed in side-by-side relation in a battery into a common waste heat tunnel leading to a common stack which provides a draft through the tunnel sufficient to maintain a subatmospheric pressure in the coking chambers of the ovens. A substantially closed shed extends over the coke guide and quench car tracks along the entire length of the battery for confining particulate and gaseous emis- sions released during pushing of coke from the ovens. A plurality of conduits provide fluid communications from the interior of the shed to the waste heat tunnel to enable emissions to be drawn from the interior of the shed for incineration in the waste heat tunnel. Valves in the con- duits are operable to open the conduits during pushing of coke from the ovens and for closing the conduits after completion of the pushing operation.
