Ground coke
Thread Content
In production, coke often falls onto the quenching tracks. I wonder if you experience this issue as well – do you have a specific plan for cleaning it up? How can this phenomenon be avoided?
This phenomenon occurs under normal circumstances; it is mainly due to the coke that falls off during the process of transferring coke by the coke catcher and the coke quencher. The only solution is to improve the sealing between these devices, but this is not easy to do
It is inevitable for a small amount of coke to fall on the quenching track; regular inspection of the track is the main solution.
Apart from spills that occur during the coking process, carbon spillage can also be caused by defects in the walls of the coking car; manual cleaning is required. In our factory, cleaning is generally carried out once in a while during shift changes
I strongly agree; this phenomenon occurs in basically all coking plants. However, through equipment upgrades, less coke is produced.
Ours are cleaned regularly, and also, we try to be careful during the handling process to avoid excessive spillage
We conduct shift handovers and inspections on a daily basis; cleaning must be completed before leaving work! :)
There are generally two reasons why coke falls onto the tracks of the coke quenching car； 1. There is a problem with the stroke of the coke pushing rod; after coke pushing is completed, some coke remains in the coke guide grid. After the coke quenching vehicle moves away, the coke falls onto the tracks of that vehicle as the coke stopper moves. The stroke of the coke pushing rod can be adjusted, or the angle can be increased by modifying the last wear-resistant plate in the coke guide grid, so that the coke can fall naturally into the coke quenching vehicle. 2. The seal of the coke discharge door on the coke quenching vehicle is not tight, resulting in significant leakage of coke during movement; it is necessary to consider the stroke of the cylinder or adjust the size of the wear-resistant plate on the coke discharge door to ensure better sealing.
If it’s a problem with the quenching car’s compartment, then the quenching car needs to be overhauled. If it’s related to the strength of the coke (such as broken pieces or excessive coke dust), it depends on whether your plant’s coal supply can solve this issue. It is common to find some coke powder and broken coke on the tracks of coke quenching cars; almost all the plants I’ve seen have this issue. In our factory, cleaning is carried out during the scheduled maintenance periods for each shift; it’s easier in summer, but in winter everything is frozen, so pneumatic hammers and forklifts are needed.
There’s no good way; just clean it regularly at each shift.
Leakage between any processing steps is determined by whether the interfaces are handled properly; if the interfaces are well managed, there will naturally be less coke. Of course, necessary cleaning is still required.
It is inevitable for coke to fall to the ground; the only solution is to improve coordination between the coke catchers and the coke quenching vehicles, as well as to carry out regular inspection and maintenance of the equipment.
This situation is inevitable; we can only improve the operations to reduce the amount of coke produced. Here too, we clean everything up at the end of each shift
Our company also has this problem, but we have dedicated staff assigned to clean it up, doing so once a day. It’s actually a very simple task; in fact, with daily cleaning, there isn’t much residual coke left
1. Divide the tasks evenly among the four classes, with each class responsible for its own section and completing the tasks on time. 2. During shift handover, the current shift should conduct a thorough cleanup. 3. Daily shift handover inspections are required; work can only be finished once cleaning is completed. 4. Remove ice from the tracks in winter promptly to facilitate the removal of residual coke. 5. When cleaning coke, at least two people should work together under a mutual supervision system to ensure the safety of one another. 6. The personnel responsible for removing residual coke should communicate with the driver of the coke quenching vehicle, asking the driver to drive slowly while sounding the warning horn.

Our coking plant has designated personnel to carry out cleaning
