Jun 18, 2012· The boiler drum separates steam from water and contains inventory to accommodate operational changes. Water enters the riser tube, is heated, and undergoes a transition from a single-phase liquid to a mixture of saturated liquid and steam. As heat input increases, the proportion of steam vapor in the riser tube increases.

It includesmost steam boilers, the exception being those of the ‘once through’ or coil type, where there is no steam drum. In such cases, steam outlet temperatures exceeding a pre-set value are taken to indicate insufficient water input. In most cases, the simple gauge glass on the steam / water drum or boiler shell is used as the indicator.

The steam drum is the primary interface between water and steam. In a coalfired plant, boiler feedwater passes through the economizer and into the drum where the steam separates from the feedwater and is drawn off to the superheater. In combined-cycle operations, a Heat Recovery Steam Generator (HRSG) serves the same purpose as a boiler.
