Boilers are sometimes called steam generators, and Cyclone Power Technologies has used the term "Combustion Chamber/Heat Exchanger" or "CCHX". Regardless of the name used, if the system pressure is greater than 15 psi (1 bar) and heat is added, the device is legally a boiler.

Cascade, Feed Forward and Three-Element Control controlguru. By Allen D. Houtz 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.

This packaged controller includes a main control system, plug-in flame sensor modules, a UV detection system, and a UV self-check. Control and monitor up to 20 individual gas, oil, or combination gas/oil burners connected to a common valve train. Detects responsible boiler in the event of flame failure. Optional MB510 remote alpha-numeric display.

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.
