double drum steam water tube boiler

Steam drum - Wikipedia

A steam drum is a standard feature of a water-tube boiler.It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.

Steam Drums - mechanical steam-water separators

In small, low pressure boilers, steam-water separation can be established with the use of a large steam drum approximately half full of water.Natural gravity steam-water separation can be sufficient for this case. On the other hand, for high capacity, high pressure (HP) boilers, steam-water separation at the steam drum is accomplished with the use of mechanical steam-water separators.

Steam Generator vs. Steam Boiler | Powerhouse

The water flows through the smaller diameter boiler tubes while the combustion gases travel around them to transfer heat to the water. The boiler tubes in the watertube design carry the heated water inside the tubes between the lower drum (mud drum) and upper drums (steam drum), with the generated steam accumulating in the upper drum.

Bi-drum and Single Drum Boilers - Bright Hub Engineering

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.
