  • Three Element Drum Level Control - CrossCo

    How can steam drum level be controlled to maximize both stability and responsiveness? 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.Learn More

  • 3-Element Boiler Feed Water Control • Strategic Automation

    The following three inputs are required for implementing 3-element BFW control: Steam drum level; Boiler feed water flow; Steam flow; Single-Element BFW Control. The steam drum level indicates the flow imbalance between the BFW supply and steam production. Therefore, to maintain BFW inventory, the boiler controls include a steam drum level Learn More
