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.
In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. High Pressure Water Tube Boiler: The heated water then rises into the steam drum. Here, saturated steam is drawn off the top of the drum.
