Product Description
Pressure Vessel Boiler Steam Drum Fire / Water Tube ASME Certification
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.
Application
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.
Function
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.

Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification
Boiler Industrial SA210A1 Steel Boiler Economizer Heat Exchange Part ASME Certification Introduction The H-shaped finned tube is also known as the H-shaped fin tube, also known as the butterfly fin tube. It is to weld symmetrically two pieces of steel with an arc in the middle to form fins (ribs or butterflies), the frontal shape of which resembles the letter "H", so it is called the H-shaped finned tube. The two fins of the H-shaped fin tube are rectangular and approximately
