On the temperature resistance of the furnace tubes in diesel hydrofining reactors
Thread Content
I would like to ask the fellow sailors here: does anyone know the temperature tolerance range of TP321 material for the radiant furnace tubes in diesel hydrogenation unit reactors? Thank you!
Does the OP work in diesel hydrogenation? What type of process? :victory:
Generally, the temperature of the furnace tube should be below 800 degrees.
The TP321 material is 18Cr-10Ni-Ti (sometimes described as 0Cr18Ni10Ti); its maximum operating temperature is 815°C； Design metal temperature: 815 °C ； Antioxidant limit temperature: 850–900 °C
:Shut up: Is the maximum wall temperature value of 415°C provided by that design institute too conservative? ?
The general requirement is that the wall temperature should be below 550 degrees; are your conditions related to the temperature at the furnace outlet?
It’s not possible to state generally what the temperature tolerance is. It is recommended to study the following standards carefully: http://bbs.hcbbs.com/viewthread.php?tid=8609&highlight=3037
