Issues regarding the wall temperature of the heating tubes in delayed coking units
Thread Content
By chance, I saw that the wall temperature of a delayed coking heater was close to 700°C. When I asked about the material of the furnace tubes, I was told it was P9. Experts, what is the maximum continuous operating temperature for this P9 material? Given the current wall temperature, can the heating furnace continue to operate?
The maximum continuous operating temperature for P9 tubing is typically around 650°C. If the wall temperature approaches 700°C, there is a risk of exceeding the recommended operating temperature, and long-term operation may lead to a decline in material properties and a reduced lifespan. It is recommended to check the operating condition of the heating furnace, and consider taking cooling measures or replacing the pipes. .
The temperature is too high, which indicates severe coking and requires treatment
