combustion of # 2 fuel oil with Chlorides

combustion of # 2 fuel oil with Chlorides

(OP)
hi there,

anybody has experience of combustion of # 2 fuel oil with Chlorides (50 ppm).
we want to use this fuel in water tube boiler. tubes are plain carbon steel.
Chorides will combine with moisture to form HCl - this would happen when flue gases reach below dew point, but what would happen in the combustion chamber at high temperature (from 800 to 1800F)?
any experience, suggestions ?
regards,

RE: combustion of # 2 fuel oil with Chlorides

The only concern I have heard with acid corrosion is in the economizer section if the gases or the tube wall temperature drops below the acid dewpoint temperature.  I have not heard of corrosion problems with hot HCl in the radiant or superheater sections.
