Subcritical Recirculation Boiler Steam Drum Carbon Steel 96mm Thickness
Subcritical Recirculation boiler steam drum carbon steel 96mm thickness
Drum saturated steam is separated from the steam-water mixture discharged from the risers in its steam space and in the separating equipment installed in it.The steam drum is also a water storage vessel which accomodates the changes in water level during load changes and internal water treatment;therefore the steam drum size must be large enough to house the separating equipment and to contain the required quantity of water.
Functions
• Separation of saturated steam from the steam-water mixture produced by evaporating tubes.
• Mixing feed water from economiser and water separated from steam-water mixture,and re-circulate through the evaporating tubes.
• Carrying out blow down for reduction of boiler water dissoled solid concentration.
• Treatment of Boiler Water by chemicals.
