AUXILIARY POWER UNITS - NASA

AUXILIARY POWER UNITS The auxiliary power unit is a hydrazine-fueled, turbine- driven power unit that generates mechanical shaft power to drive a hydraulic pump that produces pressure for the orbiter's hydraulic system.There are three separate APUs, three hydraulic pumps and three hydraulic systems. Each auxiliary power unit and its fuel system are located in the aft fuselage of the orbiter.

Auxiliary Boiler on Ships - Marine Engineering

In a system associated with an auxiliary boiler, as on a motor ship, the drain tank or hotwell will be open to the atmosphere. Such a feed system is therefore referred to as 'open feed'. In high-pressure watertube boiler installations no part of the feed system is open to the atmosphere and it is known as 'closed feed'.
