The furnace door was left open for too long
Thread Content
What are the hazards resulting from the smoke guide car or coke quenching car being delayed, causing the coke pusher or coke stopper to open the furnace door prematurely, which leads to the furnace door remaining open for too long?
The forum is actually that indifferent – no one reads it, no one replies.
Removing the door too early without pushing out the coke is problematic; machine measurements show that the area on the coke side can’t handle it. Equipment such as those for dust removal above and those at the ground level also can’t cope with it. It’s necessary to adjust the gas supply in the basement. Moreover, the coke side is prone to collapse, which makes it difficult for the workers behind the furnace to work there, haha. Finally, the managers from the Safety and Environment department as well as the Production department can’t tolerate this situation – the boss gets angry, and the next day the supervisor is reprimanded. The team leader imposes strict assessments, which the workers and staff can’t stand
If the drum cooling section were under the management of the coking plant, problems would basically be resolved internally. If there’s no problem, it’s just dismissed; there are fluctuations in the pressure of the gas collection system, and the oxygen content in the gas increases. Issues such as fluctuations in suction pressure ahead of the fan – it’s best to ask the operators in the drum cooling section
There is no reasonable explanation; it’s a violation of procedural rules, so one must face evaluation and punishment
Apart from the equipment and personnel on the 3rd floor being unbearable, it also affects the quality of coke, resulting in high ash content.
Coke loses weight on ignition, ash content increases, and the furnace mouth bricks are prone to erosion due to cooling.
1. Burning some of the coke leads to an increase in coke ash, which affects the quality of the coke. 2. The clay bricks at the furnace tip are prone to erosion. 3. Gas is lost and the heating regime of the coke oven is disrupted. 4. Burning of the burner and the graphite in the horizontal flue causes leakage at the burner and furnace walls. 5. The iron components used to protect the furnace are prone to thermal deformation, especially the large springs at the top. 6. It causes the temperature at the top of the furnace to rise, as well as the temperature of the rising tube, which may even lead to its damage. In short, this method of operation is destructive and poses severe risks.
If the furnace has not been used for an extended period, the upper furnace door should be checked promptly
Environmental pollution is a certainty; leaving it open for an extended period can also cause the coke to overheat.
