Pressure Vessel Boiler Steam Drum Fire / Water Tube ASME Certification

Pressure Vessel steam and water separation Metallurgical Industry ASME certification manufacturer


Steam drums are a regular feature in many boiler systems. The steam drum provides a space for the saturated steam generated in the tubes and for the separation of moisture from the steam. It is a reservoir of water/steam at the top end of the water tubes in the water-tube boiler. Steam drums store the steam generated in the water tubes and act as a phase separator for the steam/water mixture.


1. To mix the saturated water that remains after steam separation with the incoming feedwater.
2. To mix the chemicals that are put into the drum for the purpose of Corrosion control and water treatment.
3. To purify the steam by removing contaminants and residual moisture.
4. To provide the source for a blowdown system where a portion of the water is rejected as a means of controlling the boiler water chemistry and reducing the solids content.
5. To provide a storage of water to accommodate any rapid changes in the boiler load.


1. It prevents the carry-over of water droplets into the superheater, where thermal damage could result.
2. It minimizes the carry-under of steam with the water that leaves the drum, where this residual steam would reduce the circulation effectiveness of the boiler.
3. It prevents the carry-over of solids. Solids are dissolved in the water droplets that may be entrained in the steam if not separated properly. By proper separation, this prevents the formation of deposits in the superheater and ultimately on the turbine blades.

Water circulation

Natural Circulation

In this circulation, the water flowing from upper drums through downcomers which is located in the boiler is relatively cold, flow down to mud drum. From mud drum, water flow back into the steam drum after passing through the evaporator tubes.

Forced circulation

In this forced circulation, fluid is pumped through the evaporator. This causes the boiler can work with very high pressures.
