COKE OVEN FUMES CONTROL SYSTEM ABSTRACT A contaminant capture system for a coke oven pushing operation is provided. The system includes suction means, a duct and means for coupling the suction means to the duct for evacuation thereby. The duct is of a type including a wall portion closed by a flexible web. A car is disposed for movement along the duct to raise the web to couple the interior of the car to the interior of the duct. A mobile hood is supported by the car over the conveyor of incandescent coke for withdrawal into the hood of contaminants evolved as the coke is conveyed. The duct is provided with first and second longitudinal structural means or tracks for supporting the car and the hood in a cantilever manner extending from the car over the conveyor. The duct includes a plurality of sections having at least one movable end spaced from and engaging an adjacent duct section so as to permit thermally induced variations in the length of each duct section. The longitudinal structural members of the respective duct sections are spaced from one another to afford expansion and contraction while affording travel of the car from one section to the next.
