How is the condition of the catalytic light-off heat recovery lining checked? Thank you
After turning off the light, use the naked eye to check whether the outer surface of the device is red.
Thermal inspection with the lights off involves observing whether there is any localized overheating or discoloration to a red color, allowing for an intuitive assessment of whether the lining has come loose. If it’s not possible to tell by visual inspection, then a temperature gun can be used to measure the temperature of the wall surface; generally, this temperature should not exceed 200 degrees. If it reaches 400-500 degrees, the situation is serious and weld repair should be considered. Catalyst leakage is extremely dangerous
