<P>Dear David,</P>
<P>I am trying to use a boiler to simulate the vaporization of hot water from the feedback water into steam. However, the currently library for CHP can only provide elements like Type 659a and 638 in the boilers section. For these two elements, when inlet fluid is fluid, the outlet fluid will also be fluid. Is there any way that we can set the inlet fluid to be water while the outlet fluid to be steam?</P>
<P>Thanks, </P>
