The problem of dew point corrosion in catalytic converters
Thread Content
I would like to ask: generally, the wall temperature of these two types of devices is between 150 and 200 degrees Celsius. Are there any standards or specifications related to this? It is said that dew point corrosion occurs when the temperature is below 150 degrees Celsius, but I’m a bit confused now – both units (mainly the regenerator) have insulation or wear-resistant layers, so how can dew point corrosion occur in the flue gas? What’s the process? Could it be that the smoke penetrates through the lining to reach the regenerator wall panels? Could any expert share some information on catalysis? !
Simply put, corrosion can occur from the inside out! If you don’t corrode those linings and scale meshes, how can corrosion reach the outer walls? If the external temperature is too low, does that indicate to some extent that the internal temperature is also quite low? Recommended to check out: http://bbs.hcbbs.com/thread-215885-1-1.html
