(57) An oil delivery system for supplying heavy oil from a source that is contaminated
with water to burners (34,336).
Control apparatus (8, 14) heats the heavy oil solution until it is preheated above
the saturation temperature of water at the pressure in a de-watering tank (18) which
is connected to the control apparatus and receives the preheated heavy oil solution.
The tank (18) is maintained at a pressure sufficient to permit any liquid water contained
in the heavy oil solution to vaporize and thus be removed from the heavy oil. A low
pressure pump (26,28) delivers the de-watered heavy oil from the tank (18) to a combustion
apparatus such as a marine power generator or oil burner (34,36).
