Evidence of low temperature corrosion is observed on the combustion space components of a slow- speed diesel engine. What causes this corrosion and what can one do to mitigate this situation?
A
Sulfur in exhaust gas mixing with water vapor condensation. Order cylinder oil of lower total base number.
B
Vanadium from fuel melting in the exhaust gases. Maintain lower cooling water temperature to prevent vanadium from melting.
C
Low temperature corrosion cannot be observed; it has to be determined by metallurgical testing. Maintain cooling water temperatures as per manufacturer's specifications.
D
Sulfur from the fuel condensing on cold surfaces forming sulfuric acid. Ensure cooling water temperatures maintain the combustion space temperatures above the dew point of sulfuric acid.
