ABSTRACT:
A coke dry quenching installation has a cooling chamber having a top charging opening, a travelling crane above the cooling chamber, and a coke bucket on the travelling crane movable to a position above the top charging opening and having a cover thereon. A hopper chute is positioned between the coke bucket and the top charging opening on the cooling chamber and is movable laterally toward and away from a position over the top charging opening, the hopper chute having a bottom opening which when the hopper chute is over the top charging opening is aligned in substantial gas tight alignment with the top charging opening. The coke bucket has a bottom opening which engages in sealing engagement with the top opening of the hopper chute when the coke bucket is lowered toward the cooling chamber by the travelling crane. A waste gas collecting system for the installation has a first dust collecting duct extending from the cover of the coke bucket laterally thereof, a second dust collection duct extending laterally from the hopper chute, a main dust collecting duct adjacent the cooling chamber, a first branch duct extending from the main duct and having a free end in a position where it is connected to the free end of said first duct when the coke bucket is in position on the hopper chute, and a second branch duct extending from the main duct and having a free end in a position where it is connected to the free end of the second duct when the hopper chute is in position over the top charging opening of the cooling chamber.
