[Steam-engine] Condensing Steam Cars

[Jim Showers]

    As there is a 1921 Condensing Stanlely out in the garage, I will explain 
how it works.  First the cylinder oil is different because of steam pressure 
(500-550# operating pressure) and the fact the steam is superheated.  Tallow 
is not used in the cylinder oil.
    The condensed steam with oil goes back into the water supply tank.  When 
adding water to the system, Stanley reccomended to continue adding water 
until no floating oil comes out of the overflow pipe.  It was a problem with 
condensing cars.
    I use oil absorbent sheets.  I insert one in the water tank with a short 
length of fishing line attached so it can be removed.  It absorbs the 
floating oil and very little returns to the boiler.  A sheet will last about 
200 miles.  Some guys fabricate oil separators and place one before and 
another after the condenser.  There is very little room available on my car 
to do this.
