A combination of refined oil, water and air enters the vessel, the flow is directed to the spherical end of the vessel where primary separation occurs and then flows through the vessel where it meets the coalescer. At the secondary separating section, the fluids are allowed to slow down and separate by gravity.

The operation of these level sensing devices can readily be investigated since they may be removed from the Demonstration Unit, dismantled and re-assembled, without the attendant problems which would occur on an operational boiler. The simulated boiler itself is constructed from a clear acrylic tank and thus the demonstration unit provides a clear visual appreciation of the operating characteristics of the various level controls i.e. float operated magnetic, reed or electronic system using electrode sensors. An arrangement of up to date integrated circuits is used to simulate boiler pressure and burner control together with the sensing and control systems associated with modern boiler systems. A Boiler Water Gauge is fitted to the Boiler Drum so that possible misuse of this item can be demonstrated clearly and safely. This Gauge can also be used to demonstrate the method of changing a sight glass for such a gauge under simulated working conditions, a circumstance which can be safely taught on this Demonstration Unit. These systems would not normally all be fitted in the same boiler but are included in this unit to give the student an appreciation of the characteristics of each system. Conversion of water from the boiler into steam is simulated so that the level sensors need to operate as in a true Boiler system.

The Raw Water Filtration module houses the Raw Water vessel, two independent sand filters and Filtered Water vessel. The degassed liquid is then pumped forward through the Anion Bed. The Cation Bed and Anion Bed require a regenerating every 5hours to maintain the optimum condition of the resins. Water from the Filtered water vessel is pumped forward through the Cation vessel; this then enters the degasser vessel after experiencing a carbonate removal process. Within the Acid Dosing vessel is a 5% dilution of Hydrochloric Acid, which is used to regenerate the Cation Bed. Mains water is transferred into the raw water vessel, which is then pump forward through either one of the sand filters into the filtered water vessel. On the Dosing module there is a an acid dosing vessel, caustic dosing vessel, Cation Bed, Anion Bed and Degasser vessel. In the Caustic Dosing vessel is a 4% dilution of Sodium Hydroxide; this is used to regenerate the Anion Bed.

Four independent process units demonstrate level, flow, temperature and pressure as the controlled variable.
The effect of making changes to the system or to the controller configuration can be quickly investigated by applying repeatable disturbances or step changes to the process.

Some units also cover both time proportioning and analogue control of the same parameter. Comparison of the responses obtained with different control settings clearly demonstrates the need for correct matching of the controller to the system characteristics. Each process is supplied complete with software that allows it to be controlled using a Windows PC via a USB connection.
