The furnace tubes are coiled, featuring 12 sharp bends. This post was last edited by rerakish on 2009-3-30 21:10]
A large area has died; the only solution is to replace the furnace tubes:L
Is there no other way except replacing the furnace tube?
If steam cannot pass through and it’s completely blocked, then the only option is to replace the furnace tubes!
Cut at the elbow weld and pull it to another place to burn it. Of course, the best thing to do is to replace the furnace tube. Was the most primitive form of burning not simply taking something apart, placing it on wood, and setting it on fire? Old workers have generally done it!
The problem you’re facing is indeed very tricky. In our 600,000-ton old units, if the furnace tubes get blocked, we can use a hammer to break away the blockage at the bends of the tubes and employ other methods to remove the coke buildup. The new units don’t have such blockages, but they do have a forward and reverse burning process; in case of blockage, the coke can be pushed aside to clear the path. I’m not sure what manufacturing process you use; if a large area becomes blocked, the furnace tubes have to be replaced.
Are there no more advanced technologies for furnace tubes these days? Things like mechanical tube insertion devices – I heard there used to be one company in Jinzhou that dealt with them, but unfortunately it stopped operating
There’s probably no way to replace it; why is it so serious? Didn’t you pay attention during the operation?/
Cut open the furnace tube elbows to identify the non-functional tubes; do not strike them randomly or handle them in a hasty manner, otherwise all the furnace tubes along that section will be damaged； We have encountered a similar situation during viscosity reduction; the entire second half of the furnace tube had to be discarded ；
If there’s no other way, consult the manufacturer! ! After all, they are very familiar with the detailed aspects such as the structure of the furnace tubes! During the warranty period, you can usually turn to them! !
Tap the outside to determine the approximate location of coking, cut and replace the tube, and contact the manufacturer to send replacement parts promptly.
It’s not as serious as you say. Since there’s no steam flow anymore, it seems impossible to remove the fouling by burning it off; therefore, we have to find other solutions. The simplest method for our coking unit is to make an incision at the elbow section and clean it with high-pressure water. If the fouling is severe, the pressure used must be higher. Fouling of the furnace tubes is something that happens quite often, and removing such fouling isn’t difficult. The key is to ensure that fouling doesn’t occur again in the future. It’s important to learn from the reasons behind the fouling so as to extend the operational period as much as possible. It can be used as a reference.

There isn’t enough time to replace the furnace tubes; the plant is set to start operating in about 10 days. Cutting through those sharp elbows while working with fire poses a problem, as the pipelines are blocked and it’s not possible to clear them out, and there’s a risk of gas or oil remaining inside the pipelines

Water is injected at the inlet and outlet to displace the oil and gas. If that doesn’t work, a grinding disc is used to bend the elbow, followed by another displacement process. Identify the blocked pipes; if they are long, it is recommended to replace them!
The water injection method was tried, but due to the severe clogging caused by carbonization, applying a pressure of 35 kilograms with a pressure pump had no effect at all – not much water managed to get in. It seems that the furnace tubes are blocked
I have encountered this situation; the fastest solution is to replace the furnace tube, and it is also the most cost-effective approach.
Our factory’s atmospheric pressure furnace has also encountered this issue; it took a day to replace the furnace tubes.
Mainly, the factory doesn’t have the furnace tubes in stock, and there isn’t enough time. Methods already tried: pressurizing with water at 35 kilograms had no effect, and using nitrogen at 10 kilograms for blasting also had no effect
