Device and method for sealing levelling door aperture of a coke oven chamber

A device to at least partially seal a leveler door opening of a coke oven chamber during top charging of the coking coal comprising a housing having a first end opening connectable to the leveler door opening so as to form a seal, a leveler bar guided into a second end opening and at least partially through an interior passageway of said housing and at least partially through said leveler door opening, said leveler bar including at least two side segments and at least two cross segments connecting said two side segments, said housing provided with a sealing mechanism to at least partially inhibit a flow of gases in front of said leveler door opening by creating a no-flow zone in a region in at least closely adjacent to the front of said leveler door opening, said sealing mechanism including at least one movable sealing element to at least partially seal an inner cross section of said leveler bar between said side segments and at least two sealing plates arranged in said housing, said at least one movable sealing element includes at least one pivoting seal having a pivotable panel wherein the pivotable panel is movable between at least two of said cross segments of said leveler bar, at least one cell wheel having a plurality of panels rotatable about an axis wherein at least one of said panels is movable between at least two of said cross segments of said leveler bar, and combinations thereof, said sealing plates secured to said housing and extending outwardly from said second end opening of said housing, said sealing plates at least partially sealing gas between at least two of said cross segments of said leveler bar that are spaced outwardly from said second end opening, said two sealing plates positioned substantially parallel to one another and oriented above and below said two cross segments when said leveler bar passes between said two sealing plates.

A device to at least partially seal a leveler door opening of a coke oven chamber during top charging of the coking coal comprising a housing having a first end opening at least partially connectable to the leveler door opening and at least partially encircling said leveler door opening, a leveler bar at least partially moveable into a second end opening of said housing and at least partially through an interior passageway of said housing and guidable at least partially through said leveler door opening, said leveler bar including at least two side segments and at least one cross segment connecting said two side segments, said housing provided with a sealing mechanism to inhibit a flow of gases in front of said leveler door opening by creating a no-flow zone in a region in at least closely adjacent to the front of said leveler door opening, said sealing mechanism including a regulatable exhaust fan connected to said housing to expel gas substantially comprising air through an outlet opening in said housing and a flow measuring mechanism at least partially positioned in said housing between the coke oven and said outlet opening, said outlet opening positioned between said first and second end openings of said housing, said flow measuring mechanism measuring gas flow through said leveler door opening, said flow measuring mechanism at least partially controlling said regulatable exhaust fan to control a flowrate of said expelled gas through said outlet opening so as to substantially reduce the flow of gas through said leveler door opening.

A method for at least partially sealing a leveler door opening of a coke oven chamber during the leveling process comprising:

• a providing a housing having a first end opening at least partially connectable to the leveler door opening;
• b. providing a leveler bar;
• c. moving and at least partially guiding said leveler bar at least partially through said housing and said leveler door;
• d. monitoring gas flow through said leveler door opening;
• and,
• e. at least partially regulating exhaustion of gas substantially comprising air from said housing by measuring a flow of gas through the leveler door opening and controlling a rate of said gas exhaustion from said housing in order that there is effectively no gas flow through said leveler door opening while said leveler bar moves through said leveler door opening.
