Steam Drum is the most important part of one steam boiler. It is a pressure vessel of water/steam at the top of water tubes. The steam drum stores the saturated steam and serves as a separator for steam/water mixture.
The steam drum is used for the following:
- To mix the remaining saturated water after steam separation with incoming feedwater.
- To mix the chemicals dosing into the drum for corrosion control and water treatment.
- To purify the steam by removing contaminants and residual moisture.
- To provide source for blowdown system where a part of water is rejected as a means of reducing solids content.
- To provide a storage of water to accommodate any rapid load change.
- To prevent the carry-over of water droplet into superheater and cause potential thermal damage.
- To minimize the carry-over of steam with moisture leaving the drum.
- To prevent the carry-over of solids and prevent the formation of deposit in the superheater and steam turbine blade.
Power plant boiler manufacturer Taishan Group won two sets 420t/h high pressure natural gas boiler. In early September 2021, the drum for the gas boiler finished hoisting.
We are responsible for the design, production and assembly of 420t/h high-temperature and high-pressure natural gas boiler.
