Abstract
Method and apparatus for receiving and transporting hot coke in a coke oven pushing operation and controlling emissions resulting therefrom comprising a one spot quench car having a receptacle which is tiltable to a coke receiving position, a travel and quench position, and a coke discharging position. A hood structure is provided to confine the gases during pushing and a collecting main removes the gases to a remote location for cleaning thereof.
Claims11
Apparatus located on the bench side of a coke oven battery for receiving hot coke pushed from a coke oven in the coke oven battery and transporting the coke to a quench station for quenching and thereafter to a coke wharf for discharging the coke thereon and collecting emissions resulting during the pushing cycle, comprising:
- (a) a coke guide mounted on rails for movement along the bench side of the coke oven battery,
- (b) a one spot quench car mounted on rails adjacent to the coke guide rails having a coke receptacle thereon with a top opening for admitting the hot coke, with means to tilt the receptacle towards a coke oven to be pushed to a coke receiving position, maintain the receptacle in a vertical upright travel and quench position, and tilt the receptacle towards the coke wharf to a coke discharging position,
- (c) a hood structure mounted on the coke guide to enclose the top opening of the quench car and the coke guide when the coke receptacle is in a coke receiving position,
- (d) means actuated by the tilting of the coke receptacle to the coke receiving position to sealingly engage the hood structure with the coke receptacle, and
- (e) means to collect emissions generated within said hood structure during the pushing of the coke oven.
Apparatus located on the bench side of a coke oven battery for receiving hot coke pushed from a coke oven in the coke oven battery and transporting the hot coke to a quench station for quenching and thereafter to a coke wharf for discharging the coke thereon and collecting emissions resulting during the pushing cycle, comprising:
- (a) a coke guide mounted on rails for movement along the bench side of a coke oven battery,
- (b) a quench car mounted on rails adjacent to the coke guide rails with a longitudinal axis parallel to the rails and with a top opening for admitting the hot coke and having stabilizing means supported on a third rail which is parallel and adjacent to the quench car rails,
- (c) a coke receptacle mounted on the quench car with means to tilt the coke receptacle about an axis of rotation which is parallel to the longitudinal axis of the quench car towards a coke oven to be pushed to a coke receiving position, maintain the receptacle in a vertical upright travel and quench position, and tilt the receptacle towards the coke wharf to a coke discharging position,
- (d) a hood structure to enclose the top of the coke receptacle and the coke guide when the coke receptacle is tilted to a coke receiving position,
- (e) means actuated by the tilting of the coke receptacle to the coke receiving position to sealingly engage the hood structure with the coke receptacle, and
- (f) means to collect emissions generated within said hood structure during the pushing of the coke oven
The method for controlling emissions in a coke oven battery during the pushing of a coke oven therein which comprises the steps of:
- (a) positioning a coke guide on the bench side of the coke oven battery adjacent to and aligned with a coke oven to be pushed,
- (b) providing a quench car on rails adjacent the bench side of the coke oven battery having a tilting coke receptacle thereon to receive the contents of the coke oven,
- (c) providing a hood structure with movable seal means mounted thereon to enclose the coke receptacle and the coke guide,
- (d) tilting the coke receptacle toward a coke oven to be pushed to force the coke receptacle against the movable seal means,
- (e) discharging the contents of the coke oven into the coke receptacle,
- (f) collecting emissions generated within said hood structure during the pushing cycle of the coke oven,
- (g) tilting the coke receptacle away from the bench side of the coke oven battery, and
- (h) positioning the coke receptacle in a travel and quench position.
