A cast house emissions recycle system for a blast furnace including a housing surrounding and enclosing the lower portion of the blast furnace and the tap holes and runners therefor and the hot metal ladle associated therewith, structure collecting the emissions from the housing, and a blower having an inlet duct communicating with the collecting structure and an outlet duct communicating with the cold air blast inlet to a hot blast stove for heating the air stream flowing therethrough and returning the heated air stream to the interior of the blast furnace; in an alternative construction, the output from the blower is connected to the combustion chamber of an associated hot blast stove as part of the fuel combustion air input thereto.

Cast house emissions recycle system

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.

Collection device for coke oven gases

A coke guide spray system on a coke guide disposed on a track between a row of coke side doors and a coke quenching car, the coke guide including an outer frame mounted on wheels for movement along a coke guide track and mounting on the outer frame a track carrying a coke guide chute provided with wheels engaging the track for movement toward and away from an associated coke side door, a water inlet pipe mounted on the outer frame and connected to a source of water under pressure, a first water spray mounted on the outer frame above the coke guide chute adjacent to the end thereof disposed toward the associated coke quenching car, and a second water spray mounted on the outer frame above the coke guide chute and disposed outwardly with respect to the end thereof disposed toward the associated coke quenching car; another system is provided with a hood housing, an induced draft fan and a condensing spray system, while yet another system is provided with a hood having a mist eliminator tower housing a spray condensing system and a grit filter.
