Default compound oil use when exhaust condensate back to boiler

should compound cylinder oil be used in a model steam plant if the exhaust condensate is being returned to the boiler?

there is usually some sort of oil separator scheme for the return condensate the oil in boiler feed water will cause foaming

Thank you Chrsbrbnk, so provided there is oil separation in the system compound cylinder oil is the correct lubricant

Be sure to use the minimum but proper amount of cyl. oil needed when condensing. A close friend and Liberty Ship Chief Engineer told me they would cross the ocean on less than 5 gallons of cyl. oil used in it's triple expansion condensing engine. The failure of A.D. Baker's high pressure steam tractor was the operators using too much unnecessary steam oil. It caked up in the boiler and caused tubes to fail. Bill Van Norman,near Holland Ohio, bought a new one, used it properly, and loved it. He used it for thrashing and saw milling. Never had a problem with it. Wouldn't give it up until A.D. Baker himself came to his farm and made him an offer he couldn't refuse. Bob Rosebrock currently has the factory rebuilt 21 Baker Bill got included within in the trade.

In a condensing plant with return of condensate to boiler you should only use pure mineral oil with the highest possible demulsifying qualities. The principle of oil separators is the distinction between oil and waterous phase. Some modern compressor oils will work. Compound oils will possibly have better lubricating qualities but separation from water may be impossible. The steam launch fraternity has been suffering from this problem for ages.
