Abstract
A coke guide fumes control system includes a hood overlying a coke guide and apparatus for continuously evacuating the hood during a coke pushing operation. Several types of apparatus are illustrated. Some types are self-contained, including blowers and filter mechanisms mounted on the coke guide hood. The fumes and dusts from the pushing operation are evacuated through the filter mechanism under suction established by the blower, and the purified air pulled through the blower is exhausted to atmosphere. Alternatively, the hood can include slot-like nozzles cooperating with the blower to generate an air curtain which is directed down the sides of the coke guide to prevent the escape of contaminants through openings typically provided in the sides of such coke guide. Alternatively, and/or additionally, air curtains can be directed at the coke oven door opening to prevent the escape of contaminant fumes and dusts from the space defined by the coke oven door opening, the coke oven buckstays and the coke guide hood.
