    The once through boilers do not have any boiler drum as there will be no formation of water+ steam mixture available for separation. Instead of the drum, these boilers employ separating vessels. The feed water fed to the boiler is preheated using regeneration to raise the feed water temperature and harness the heat of the extraction steam.

    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.
