Abstract
A system for preventing effluents containing coal dust from being emitted from a coke oven upon charging the coke oven with coal. A U-tube mounted on a larry car interconnects the charging oven with a coking oven and an air valve mixes air with the effluents being transferred from the charging oven to the coking oven. A venturi tube is in communication with the coking oven on the side thereof away from the U-tube and has a steam jet therein to provide sufficient draft across the coking oven to draw the effluents. The restriction in the venturi tube accelerates the effluents through the venturi tube to accommodate all of the effluents produced during the charging of the coke oven.
