  • Superheaters - an overview | ScienceDirect Topics

    The main difference between superheaters and reheaters is the steam pressure (Kitto and Stultz, 2005). In a typical drum boiler, the superheater outlet pressure might be 2700 psig while the reheater outlet pressure might only be 580 psig (Kitto and Stultz, 2005). They are used to help control steam temperatures, control steam flow pressure loss Learn More
