CONTROLLING BOILER SWELL AND SHRINK - Africa

2017-10-17 · The steam drum mass balance requires the water and steam flow to be equal, thus no gain is placed on the steam flow signal. The raw value derived from the process is used directly in the control configuration. Figure 8 shows a 10% increase in the steam flow magnitude signal. It indicates that the set-point of the feed water controller is

Steam drum - Wikipedia

2020-7-14 · A steam drum is a standard feature of a water-tube boiler.It is a reservoir of water/steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase-separator for the steam/water mixture.The difference in densities between hot and cold water helps in the accumulation of the "hotter"-water/and saturated-steam into the steam-drum.
