Superheat Steam Temperature Control

2010-8-3 · This is the method used predominantly to control steam temperatures. The basic theory of control by attemperation is that if a superheater is made large enough to give the desired steam temperature at low loads, it will give a steam temperature at high loads that is higher than that desired if there is no method of control.
