An investigation on the corrosion of flue gas sensor in boiler stack
Anees U. Malik - Saline Water Conversion Corporation
(in lingua inglese)
The sensor transducer and its external covering were found covered with contaminated deposits which are rich in sulphur. Both 316 SS covering and the transducer part made of titanium were subject to dew point corrosion originated from the sulphur containing flue gases combined to the moisture and low temperature. A galvanic corrosion between titanium (more noble) and 316 SS (less noble) is also suggested if the two metals are in mutual contact with acidic condensate.
