once-through boilers

ONCE-THROUGH BOILERS

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 …

drum type and once through boiler design

Drum Type and Once Through Boiler Design

Once-through Boiler Characteristics. The once through boiler has high load response characteristics due to the fact that it does not have a drum and has a much lower water inventory. In the once through boiler, many times the load change response is dictated by the firing system and its controls rather than the boiler, per-say.
