he double-pipe heat exchanger used in experimentation is located in MEB 3520.
Figure 7 describes the setup of double-pipe heat exchanger. Fluid from the tank is first heated in
the by steam that is condensing in the annulus and is then cooled by the four cooling-water
passes. In all instances low-pressure steam is used to heat the fluid and water is used to cool the
fluid. Once cooled the fluid is then returned to the tank.
