    At the heart of any steam generation system is the boiler/steam drum. Although it comes in many sizes, its primary and peripheral functions are as follows: providing ample surface area for the efficient separation of water and steam; providing storage capacity to meet immediate boiler feed water requirements; and facilitating the introduction of chemicals for treatment purposes, as well as the

    Jul 11, 2004 · The X holdup time is typically based on the measured liquid volume between normal water level NWL and the lo-lo water level trip . The lo-lo level is the min level needed to ensure the water flowing down the downcomers does not entrain excessive steam and thus avoid upsets to the natural circulation. This might be 12" above the drum invert, but varies according to downcomer size and water velocity …

    For example, a steam drum that is operating at normal water level has the bottom half of the drum cooled by water and the top half by air initially and steam eventually. If one starts to fire the boiler from a cold start, the water will heat up very quickly in the drum and the bottom half of the drum will expand much more quickly than the top

  • Flash boiler - Wikipedia

    A flash boiler is a type of water-tube boiler. The tubes are close together and water is pumped through them. A flash boiler differs from the type of monotube steam generator in which the tube is permanently filled with water. In a flash boiler, the tube is kept so hot that the water feed is quickly flashed into steam and superheated.
