Steam Heaters are simply heat exchangers in which one of the media is steam
being condensed while the other is a process fluid being heated. In doing
this, there is a phase change which puts special demands on the process
control system. It is difficult to generalize about the various options for
control. Special system requirements often put unexpected constraints on the
process. Even the orientation of the exchanger can have peculiar and
unexpected results.
