Engine: Motor Plants and Auxiliary Boilers

1. A Low temperature corrosion cannot be observed; it has to be determined by metallurgical testing. Maintain cooling water temperatures as per manufacturer's specifications.
2. B Vanadium from fuel melting in the exhaust gases. Maintain lower cooling water temperature to prevent vanadium from melting.
3. C Sulfur in exhaust gas mixing with water vapor condensation. Order cylinder oil of lower total base number.
4. 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.
