Measures for dealing with the high-temperature areas on the regenerator wall
Thread Content
Currently, the wall temperature of the dense phase vessel in the regenerator is quite high. How can this issue be resolved without shutting down the operation?

If the overtemperature is caused by linear cracks and the affected area does not expand, then there is no major issue with operation; just keep an eye on it. If there is one or two spotted heat areas, 316L sheet reinforcement plates can be welded outside the vessel wall. When welding these reinforcement plates, steam inlets and outlets for cooling should be installed, with a small amount of saturated steam being supplied; otherwise, the original wall plates will not dissipate heat effectively, and their strength will decrease significantly. By handling it in this way and keeping close monitoring, it can be maintained for a while. If there are many hot spots, it indicates a problem with the lining pouring; it’s better to stop work and take action.
May I ask if it is possible to weld a steel plate cover directly onto the vessel wall?
It can be welded directly to the wall of the vessel.
How is the processing going? ? Are there any pictures?
