Method for evacuating emissions of a coke oven
A coking plant handling apparatus for use with a coking plant having a battery of horizontally arranged side by side coke ovens with a quenching car trackway for a coke quenching car disposed alongside the battery outwardly of a coke cake guide car which is also movable along the ovens of the battery on a guide car trackway comprises a closed gas exhaust system which has an exhaust connection adjacent the quenching car. The support structure provides a support for a hood and a trackway for the hood adjacent the quenching car trackway and a structure is supported upon and movable along the hood support and trackway structure. The hood structure includes a first hood portion of vertically deep size which is adapted to be positioned adjacent a coke cake guide car in a position to overlie coke being pushed through the guide car into the quenching car. The hood structure also includes at least one additional hood area, advantageously one of shallow depth which is also connectable to the exhaust connection to cover a portion of the quenching car which moves beyond the first hood portion after the initial discharge of coke has been exhausted through the first hood portion. The apparatus includes additional controls and ducts connectable to the second hood portion at locations along the length of the car as it advances and with a control device arranged in the passage of the car for actuating these devices as the car is moved so as to sequentially increase the exhaust suction and exhaust area over the quenching car as it is advanced.
