  • Bi-drum and Single Drum Boilers - Bright Hub Engineering

    2010-2-19u2002·u2002Bi-drum boilers find its use in industrial steam generators very widely as they are capable of handling lot of load fluctuations. This is mainly due to the reason that the water reserve available is very high when compared to single drum. The single drum boilers can be designed for very high pressures and flows, even close to critical pressures.

    Water-tube boiler plant is much less tolerant of high TDS levels, and even less so as the pressure increases. This is due to a number of reasons, including: Water-tube boilers have a limited water surface area in the steam drum, relative to the evaporation rate. This results in very high steam release rates per unit of water area, and turbulence.
