The control of the boiler drum level is tricky and even the best tuned control systems cannot always prevent a low-water condition. The "water level" in a steam drum is actually a fairly unstable compressible mixture of water and steam bubbles that will shrink and swell with pressure changes and will actually shrink momentarily when more "cold" feedwater is added.

31/10/2012 · The control system should include a mathematical model of the boiler and a set of constraints using multivariable predictive control. This solution uses standard boiler instrumentation to derive a relative index of heat release in the furnace; once this is known specific firing rate requirements can be determined and fuel can be adjusted on a real time basis to stabilize furnace heat release.
