I need recommendations regarding the selection of thermocouples for incinerators (subject to corrosion)
Thread Content
Dear experts, the thermocouples used in our company’s salt-incineration furnaces burn out every few months (it may also be due to corrosion). Do anyone have any successful experiences using them, or are there any manufacturers capable of producing thermocouples suitable for such operating conditions? PS: The temperature in the furnace is around 1200°C, and the medium is somewhat corrosive. I have used protective covers made of stainless steel, silicon carbide, and others in the past. They all failed! Thank you all

Double-layer corundum sleeve, with a temperature resistance of 1800 degrees
I remember bg3.png – corrosion of materials at high temperatures; it is said that molecular leakage occurs in such cases? It is said that there is a type of thermocouple that is filled with nitrogen and keeps the pressure inside its protective tube at a positive level, as a way to counteract this type of corrosion.
A double-layer corundum sleeve will do; we can use one of these for several years
Try using protective tubes made of stainless steel 2520. This austenitic chromium-nickel stainless steel possesses excellent oxidation and corrosion resistance. Thanks to its high percentage of chromium and nickel, it has a much better creep strength, allowing it to function continuously at high temperatures; it also has good high-temperature resistance.
Our company specializes in the production of thermocouples designed for waste incineration. We use a double-layer protection tube: one layer is made of a special alloy, and the other layer is made of corundum. Additionally, we can provide samples for testing; payment can be made after being satisfied with the trial.
