  • Mitsubishi Power | Drum Boilers

    In a drum boiler, the circulation of water is produced through the density difference of water in the down comer pipe and the water/steam mixture in the furnace tubes. In low-pressure boilers where this density difference is large, the circulating force is high and a high volume of circulation can be ensured, but since it becomes difficult to Learn More

  • Steam-Water Circulation in Boilers | SpringerLink

    Circulation refers here to the flow of water, steam, or their mixture around the steam—water circuit in a boiler. In early days of boilers, steam was generated in a large vessel. The vessel was heated from outside, which would create a convective current within the large body of water. This process did not pose any threat to the safety of the Learn More
