By how much can the temperature be reduced with an insulating layer as a lining after acid-resistant bricks are laid?

Hello everyone. If the temperature of the reaction slurry in the reaction tank is 140°C, and the anti-corrosion solution adopted is a 5 mm thick layer of butyl rubber as an insulation layer, with 2 layers of 65 mm thick acid-resistant tiles applied on top, what would be the approximate temperature to which the butyl rubber insulation layer is exposed? How to calculate it, thank you
Let’s first understand the thermal conductivity of the material. Using some formulas related to heat conduction, it should be possible to make an estimate
It can’t be reduced much; there’s an issue with the material used.
Looking at your question... what you want to know is whether isolation and acid-resistant tiles are both used inside the reaction tank or outside it. Are you trying to avoid corrosion or achieve insulation? It’s better to first outline your goals, as that will help you think through things. Could you explain the entire sequence in detail first? Reaction tank → metal → butyl rubber → acid-resistant tiles. Then, the question is: is it the temperature at which butyl rubber comes into contact with metal, or the temperature after heat has been transferred to the butyl rubber? ------------------------------------------------- If the sequence is as I described, then is it question one or two? For question one, it’s the surface temperature of the metal after heat transfer, which is basically around 140 degrees. For question two, it’s similar... because the main purpose of butyl rubber isn’t insulation but rather preventing corrosion, right... ---------------------------------------------------------------- Acid-resistant tiles... don’t have very good insulation properties, so the overall temperature remains high. ----------------------------------------- If insulation is the goal, then it’s better to use insulation materials on the outside; there’s no need to go to such lengths...
