ONCE-THROUGH BOILERS

2/2/2011 · Once-through boilers are generally associated with high pressure operation and the feed water enters at high sub-critical (>180 bar) or supercritical pressure whilst superheated steam leaves at a pressure some 20–30 bar lower. Sliding pressure operation is adopted to accommodate requirements of part-load running.
