Boiler Fundamentals and Best Practices

Jul 21, 2012 · The level controller transmits its target flow as a set point to a flow controller. The flow controller then decides how much to open or close the valve as supply pressure swings to meet the set point target. This is a 2-element (boiler liquid level to feedwater flow rate) cascade control strategy.

Oct 31, 2019 · This level/flow cascade control system also embodies the principle of the secondary (slave) loop being faster-responding than the primary (master) loop. Water flow is an inherently fast process, the flow rate responding immediately to changes in valve position. By contrast, water level is a much slower-responding type of process.

Test Disturbance Further test the Level-Flow Cascade control system by applying a disturbance. Open or shut (one direction only) LCV31 from LIC31 in Manual (M) mode by changing MV by about 10% to 20% and quickly transferring LIC31 back to Auto (A) mode. Observed until it fairly steady, and stop the current process for shutdown procedure. 5.2SHUTDOWN PROCEDURE To shut-down the training system: Set

Nov 09, 2011 · Figure 4 presents the level-to-flow cascade control configuration. The cascade consists of two loops: 1. Inner loop. The flow controller positions the discharge control valve so discharge flow is at or near the set point provided by the level controller. 2. Outer loop. The vessel level controller provides the set point to the discharge flow controller.

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).
