Introduction. Controlling the boiler feed water (BFW) level in a steam drum can be difficult. The level indication is affected by changes in the steam drum pressure as well as changes in BFW inventory. The pressure changes can cause shrink and swell, which can cause the level controller to adjust the BFW flow …

21/7/2012 · Cascade, Feed Forward and Boiler Level Control. July 21, 2012 by Rishabh Mishra. 1. One common application of cascade control combined with feed forward control is in level control systems for boiler steam drums. The control strategies now used in modern industrial boiler systems had their beginnings on shipboard steam propulsion boilers.

Cascade, Feed Forward and Boiler Level Control – …

The flow controller will adjust the boiler feedwater valve position to restore the flow to its set point before the boiler drum liquid level is even affected. The level controller is the primary controller (sometimes referred to as the master controller) in this cascade, adjusting the set point of the flow controller, which is the secondary controller (sometimes identified as the slave controller).
