Boiler Drum Level Control | Yokogawa Electric Corporation

This three-element controller is a so-called cascade controller in which a drum level control unit is cascaded into a feedwater flow control unit. Single-element Control: During startup of a boiler, both the feedwater and main steam flow rates remain below the measurable ranges, and this makes the three-element control with a level controller and flow controller unstable.
