Steam drum is a collection vessel for steam & water. Here water & steam is separated. It has steam separators.
In localities where the water supply carries large quantities of clay or loam in suspension, a boiler with a mud drum or sediment chamber, Fig.. 131, should be used. The boiler will then serve as a settling basin and most of the suspended matter will settle to the bottom of the boiler and into the sediment space.
Conversion of water into steam is the primary function of a utility boiler. The steam pressure is used to turn a steam turbine thus, generating electricity. Within the boiler drum there exists a steam/water interface. Boiler steam drum water level is one of the important parameters of power plant that must be measured and controlled.

This will allow gas bubbles to rise to the drum rather than collecting where there should be water. The transmitter can be scaled either 4 mA at zero DP (drum full) or maximum DP (drum empty). But the CCS (combustion control system) should scale the raw input so that it reads zero when the drum has cold water at the design operating level
Mar 13, 2016 · Cyclones or agglomerators are part of what are called the "internals" of the steam drum. The primary function of the steam drum is separate water from steam which prevents carryover of the condensate into to the steam header (phase separation).

Using the operating point search function, the example illustrates model linearization as well as subsequent state observer and LQR design. In this drum-boiler model, the control problem is to regulate boiler pressure in the face of random heat fluctuations from the furnace by adjusting the feed water flow rate and the nominal heat applied.
