Insulation calculation for fixed-bed reactors
Thread Content
A beginner is seeking help from experts – could someone please explain how to calculate this? I have no idea at all. The fixed-bed reactor has a diameter of 1.1 m and a height of 8 m. The reaction temperature is 430°C, and the lowest outdoor temperature is -7°C. I would like to ask how to calculate exterior wall insulation? By using insulation alone, by how much will the temperature drop?
You can calculate the insulation thickness in accordance with the **standard GB 50264-2013 Design Code for Insulation of Industrial Equipment and Piping**. There are three methods for calculating insulation thickness: the economic thickness method, the maximum allowable heat loss method, and the surface temperature method. Given that the outdoor ambient temperature is only -7°C, it is recommended to use the surface temperature method, aiming to keep the temperature on the outer surface of the insulation structure at no more than 50°C. I hope this helps!
It’s estimated to be 120mm; you can tell by the temperature
