3 ELEMENT DRUM LEVEL CONTROL

· The term 3-element control refers to the number of process variables (PVs) that are measured to effect control of the boiler feedwater control valve These measured PVs are: liquid level in the flow of feedwater to the boiler drum and flow of steam leaving the boiler drum Maintaining liquid level in the boiler is the highest priority

Three Element Drum Level Control - CrossCo

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
