Abstract
A pollutant collection and exhaust system is provided in a battery of coke ovens for removal of atmospheric pollutants from the gases released at the time of discharge of coke from an oven. A coke guide carriage is provided with an exhaust hood which encloses the coke guide and extends over the transfer car thereby enshrouding the discharging coke and resulting fumes and smoke during the discharge operation. The exhaust hood is movable along the length of the oven battery. A stationary exhaust manifold extends along the battery in spaced relation above the oven exhaust hood. The exhaust hood is equipped with connecting means which are adapted to register in coplanar sealing engagement with selected gated openings in the manifold while simultaneously opening the selected gates. Pollutants are exhausted from the discharge site and conducted through the manifold and associated treating apparatus with draft induced by an exhaust means connected to the manifold and treating apparatus.
