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.

Drum Level Control

Damage to the steam drum, boiler and turbine can result from inaccurate drum level measurement and control. If the drum level falls below setpoint, there is risk of the boiler running dry. If the level is higher than setpoint, there is risk that wet steam could carry over to the turbine, causing damage to the turbine blades.

Boiler Drum Level Transmitter Calibration - Technical Note

Steam Drum Level is both a critical and difficult measurement to make. Control of the water level in the drum must be precise.
