Is it okay to not need insulation outside the reformer?
Thread Content
Our company's converter was installed with insulation. Due to external conditions, the insulation part was damaged, and the temperature of the jacket water of the converter sometimes exceeded the target. I want to remove the insulation. Is it okay to remove the insulation? What impact will it have on the converter and its operation?
It’s okay to not need insulation outside the reformer, but we won’t use it here.
There's no big problem after removing it. It's just that it uses a lot of heat when it's new.
The outside of the reformer is usually water jacketed, which is of little use for thermal insulation.
The reformer has a water jacket and does not need to be insulated, as long as the surface is protected against corrosion.
I think it should be insulated. Insulation saves energy while driving and also protects you afterward.
The water jacket should be insulated to prevent the water jacket from overheating when the circulating water is cut off, and people getting burned when going up to open it.
Is the poster talking about the reformer used in the production of methanol from coke oven gas? This type of reformer generally does not have external insulation because it is lined inside and water jacketed outside, so there is no external insulation.
No need to keep warm. The water jacket outside the lining is used for cooling. When producing in the northern region in winter, if there is no insulation, attention should be paid to anti-freeze during short stops.
I'm in Yutian* Yes, theirs is not insulated, but the ones in our factory are insulated. I feel there is not much difference between the two
Safety means that employees will not be harmed when making mistakes, so the water jacket should be insulated to prevent personnel from being scalded. This is the safe attitude.
There is no need to install insulation. When the temperature is low at first, the water in the jacket does not need to circulate. When the temperature is high, it can be circulated accordingly. The outer surface of the conversion furnace only needs to be anti-corrosion. The water can also play a certain role in insulation when it is first started. If insulation is added, when the temperature is high in summer, the amount of water circulation must be increased to cool down and protect the furnace wall. The jacket water eventually reaches the deoxidation tank, which cannot be used. Isn’t it a waste of water? Therefore, it is not appropriate to add thermal insulation in terms of energy saving or convenient operation.
It should be insulated to prevent employees from getting burned. The temperature inside the furnace can be maintained while driving. The temperature of the water jacket is normal as long as it does not exceed 50 degrees. It is also a protection for the carcass of the reformer.
It's okay to not insulate, but I think insulation is also beneficial. Driving in different seasons with insulation will save energy. Although driving is not a common thing, the greatest benefit will be achieved by reducing energy consumption and reducing production energy consumption, right? ? ?
Each factory can decide this based on specific circumstances, and may or may not add an insulation layer. However, adding insulation layer is better than not adding it. It saves energy when driving, and also plays a protective role after driving.
I don't know if your geographical location is north or south. During normal production, the reformer does not need to be insulated, but if you are in the north, freezing blockage may occur when parking, which will bring serious hidden dangers to production safety and cause major accidents! My suggestion is that insulation is still necessary. If your water temperature exceeds the standard, it is useless to just remove the insulation to cool down. You must also find out the reason! A glimpse into the world!
Removing the insulation will not affect the operation. There has been no problem without insulation when we put it into production.
Removing insulation is not the fundamental solution to solve the over-temperature of jacket cooling water, nor is it a scientific attitude. I personally think it is necessary to find out the root cause of over-temperature or vaporization of jacket water. The overtemperature of the cooling water in the water jacket may be due to: 1. In the later period of catalyst use, the furnace temperature increases ； 2. The production load is too high, and the reformer is overloaded ； 3. Jacket water deflection ； 4. Insufficient water supply to the water jacket ； 5. The jacket cooling water return pressure is too high ； 6. The thermal insulation lining of the conversion furnace is damaged or partially peeled off. ； 7. Abnormal local temperature of the reforming furnace, etc.
This type of reformer generally does not have external insulation, but is lined on the inside and water jacketed on the outside.
It’s okay not to need insulation, but with a water jacket. We have not done any insulation since we started production in 2007.
If it is a reformer used to produce methanol from coke oven gas, it is not necessary. However, to be on the safe side, you can consult the refractory manufacturer or design institute that lining your reformer, because they have theoretical data on these.
