Annual maintenance plan for coking plant shutdown
Thread Content
Dear friends, our factory is a new coking plant that has been in operation for more than a year. It is now preparing to stop production for annual maintenance. I have just started working and have no practical experience. I was assigned to formulate an annual maintenance plan. Now I have a headache. Please give me your guidance and share your experience. Thank you. First of all, thank you for your enthusiastic participation and guidance. I did not make it clear. The main reason is to stop production and maintenance of equipment, not the coke oven body. This post was last edited by yuanbenx on 2008-1-14 16:01 ]
； Coke oven gas can be released ； Coke ovens adopt thermal insulation measures to keep them warm. The specific implementation plan depends on how long your factory plans to take? Generally, the most taboo thing about coke ovens is frequent heating and cooling. I can't explain it in one sentence. I recommend a book called "Special Operations of Coke Ovens - Oven Start-up, Stuffing, and Insulation", which is available in the forum.
I seem to have seen some information on this in the forum, so take a look and look for what you should have! Hope you get what you want!

Is the coking plant due for annual repairs after more than a year? ? ? Isn't it a major overhaul? If it's just a minor repair, it's easy to handle. But I think what you mean is a major overhaul and production reduction. If the inside of the coke oven is not involved, there is no need to overhaul it, which will be very expensive and laborious. The most important thing is that the coke oven cannot withstand the torment. If it's just an external problem, just do a good job of hot repair.
Will the coking plant stop production for maintenance after one year? Which part is to be overhauled? It is best for the poster to write down the current situation of your plant. Whether it is to overhaul the furnace body or other equipment, the plan will be different.
It’s impossible to stop production and overhaul in one year, right? Be sure to explain the question clearly
Equipment maintenance: Is it maintenance of mobile coke oven equipment? Hydraulic switch maintenance or chemical workshop equipment maintenance ； If it is a coke oven mobile equipment maintenance, it is enough to appropriately reduce production to ensure stable coke oven production. ； If it is a replacement equipment maintenance, consider stopping the coke oven insulation during heating. ； The maintenance of gas purification equipment should also specify whether it is the cold drum section or other sections. During the maintenance of the cold drum section, the coke oven production must be stopped. Other sections can appropriately reduce the coke oven production to maintain sufficient heating of the coke oven gas. The specific plan depends on the specific equipment maintenance scope.
I don’t know whether you are inspecting coke oven equipment or recycling equipment, and how long the inspection will take. Coke oven equipment maintenance (such as: If the outlet cooler and blower are inspected, the coke oven gas can be vented. Only blast furnace gas is used for heating. If it is repairing parts such as rough recycling, the coke oven gas can be bypassed.
1. Keep the coke oven in a stuffy state to prevent the furnace temperature from dropping.； 2. Gas system pipelines and equipment are purged in sections to maintain sufficient steam pressure (generally 0.5-0.6MPa) ； 3. If there is a large-scale fire, provide safety supervision
