Abstract
A method and apparatus for quenching metallurgical coke made in a coking oven. The method includes pushing a unitary slab of hot coke onto a substantially planar receiving surface of a hot car. The hot car containing the coke is then transported to a quench car station. The unitary slab of hot coke is pushed onto a substantially planar receiving surface of a quench car at the quench car station. Quenching of the slab of hot coke is conducted in the quench car with a predetermine amount of water. After quenching, the quenched coke is dumped onto a receiving pad for collection thereof.
Claims24
A method for quenching metallurgical coke made in a coking oven, the method comprising the steps of:
- pushing a unitary slab of hot coke onto a substantially planar receiving surface of a hot car;
- transporting the hot car to a quench car station;
- pushing the unitary slab of hot coke onto a substantially planar receiving surface of a quench car;
- quenching the slab of hot coke in the quench car with a predetermine amount of water;
- dumping the quenched coke onto a receiving pad for collection thereof.
A method of making coke from coal, the method comprising the steps of:
- burning a bed of coal in a coking oven for a period of time and under reducing atmosphere conditions to provide a unitary bed of coke;
- removing a product door from a product end of a first coking oven;
- positioning a hot car adjacent the product end of the first coking oven;
- pushing the unitary bed of hot coke onto a substantially planar receiving surface of the hot car;
- transporting the hot car containing the unitary bed of hot coke to a quenching car station;
- reinstalling the product door onto the product end of the first coking oven;
- pushing the unitary bed of hot coke onto a substantially planar receiving surface of a quench car;
- quenching the unitary bed of hot coke in the quench car with an amount of water sufficient to fracture substantially all of the unitary bed of hot coke and to cool the hot coke to a predetermined temperature;
- and
- dumping the quenched and cooled coke onto a coke receiving pad.
A hot car for a coke oven, the hot car comprising,
- a partially enclosed hot box having a substantially planar coke slab receiving surface;
- and
- an elevation and translation mechanism for elevating the hot box and moving the hot box toward and away from the coke oven.
A stationary pusher for pushing a substantially unitary coke slab off of a hot car onto a quench car, the pusher comprising:
- a water cooled ram head, a first arm attached to the ram head, and a second arm pivotally connected to the first arm;
- a gear drive mechanism for moving the first and second arms;
- a cooling spray system for cooling the hot car movably attached adjacent to the ram head;
- and
- a guiding track for guiding movement of the second arm from a substantially vertical position to a substantially horizontal position.
A multifunction quench car comprising:
- a tiltable receiving bed having a substantially fixed end wall, a substantially fixed side wall, a movable side wall and a movable end wall;
- and
- a tilting mechanism for tilting the receiving bed in a first direction for quenching coke and in a second direction for discharging quenched coke onto a coke receiving dock.
