LAUNDRY ADVANCED SYSTEM
EQUIPMENT DESCRIPTION AND DATA -- Continued
An oil--fired heater is used to generate the heat needed to boil water in the still and to heat the air used to dry the
laundry. The heater uses an electric blower to draw in outside air. A screen is used to prevent debris in the air from
entering the blower. The air is mixed with JP--8 and ignited to generate a flame inside the heater. The heater exhaust
air is then used to heat thermal fluid that is moving through the heater coil.
The hot thermal fluid is circulated to heat exchangers in the washing/drying drums and still by the thermal fluid pump.
An expansion tank is used to store thermal fluid and provided a place for the fluid to expand when it gets hot. The
tank has a fill port to facilitate servicing of the thermal fluid.
