  • Steam Boiler: Water Drum of Steam Boiler

    A steam drum is a pressure chamber of a steam boiler located at the upper extremity of steam boiler circulatory system. It is a reservoir of water/steam at the top end of the water tubes. The steam drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture. Steam is separated from the water and then discharged at a position above the water level …Learn More

  • What is Carryover | Causes of Carryover - Leaders in Steam

    Operating the boiler at pressures significantly lower than design pressures is a cause of carryover. Lower the steam pressure more will be the specific volume of the steam inside. Hence, the steam velocity in drum internals would be more at lower pressures. This will hamper the separation of water droplets from steam which results in carryover. 2.Learn More

  • Steam Drums | Boiler Drum | Boiler Steam Drums - Dyna

    Both types of steam drums have the primary and critical purpose of the mechanical phase separation of the water and steam mixture which flows from the Heat Recovery System Generator (HRSG) evaporator into the drum or fired boiler.
