Problems with the furnace tubes in coking heaters

Our heating furnaces have severe oxidation of their linings; we’re really worried that one day these linings might break, leading to a leak of raw materials and a fire in the furnace. It’s very concerning, but the company has no plan to carry out repairs. How can we solve this problem and prevent such situations from occurring?
How serious is it? Is it falling down in a rustling manner, like dandruff? ? The material of the furnace tubes is chosen with consideration for the corrosiveness of the feedstock and the operating conditions at high temperatures; unless the properties of the feedstock are extremely poor or there are issues with the material of the furnace tubes, tube rupture is unlikely to occur···
Ensure that no temperature points in the furnace exceed their allowable limits; identify the most problematic pipelines and reduce the temperature and flow rate for those lines as appropriate. Additionally, conduct more inspections and observations
It’s not as scary as you think. The front furnace tubes of ours also had severe peeling, and we checked them right when we stopped production for maintenance; everything is fine.
It is crucial to make the company’s leadership aware of the seriousness of the issue; otherwise, if an accident does occur, who will be able to take responsibility for it?
