Drum Level Control Systems Guide in the Process Industries

Each boiler has a boiler master, which is an A/M/Bias station that handles the firing rate for that boiler. In AUTO, the boiler master receives the plant master output, biases it, and sends that % to the fuel and air flow controllers. In MANUAL, the boiler master output is adjusted by the operator.

In this type of system the feedpump runs continuously, and an automatic valve (between the feedpump and the boiler) controls the feedwater flowrate to match the steam demand. When operating correctly, modulating control can dramatically smooth the steam flowrate chart and ensure greater water level stability inside the boiler.
