2017-1-24 · One is the water tube steam drum and the other is a waste heat steam drum. 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
Bi-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.
