Boiler drum level control is necessary to feed water into the boiler as steam is output into the header and to the associated process equipment. For a given volume of steam and blowdown leaving the steam drum, an equal amount of water should replace in the boiler. There are three main control options available for drum level control, Single

B. Three Element Control The drum level is affected by fluctuations in the main steam flow. Typical three-element control shown in fig.5. To make the feed water flow rapidly follow the main-steam flow, three-process signals-drum level, feed water flow and main steam flow signals are used. This is called three element control of deviation signal

The best method is to feed forward (FF) the steam flow to the level PID loop and cascade the output of that loop to the setpoint of a boiler feedwater (BFW) flow loop. This arrangement is called "Three Element Drum Level Control" (3E) because the algorithm uses level, BFW flow, and steam flow.

What is a three-drum boiler? - Boiler basics - ZOZEN Boiler

Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.
