Description

Heating a liquid over a heating surface produces different modes of boiling dependent on the
heat flux density. They can accelerate the evaporation process (nucleate boiling) or impair it
(film boiling). In practice, a limitation of the heat flux density must be assured in order to
prevent damage to the heating surface. This knowledge is applied in practice e.g. when
designing steam boilers for steam-powered drives. The SMT-HT-24 experimental unit can be
used to demonstrate boiling and evaporation processes in a straightforward manner. The
processes take place in a transparent tank. A condenser in the form of a water-cooled tube
coil ensures a closed circuit within the tank, whereby the evaporation process takes place at
much lower temperatures and a lower heating power. Sensors record the flow rate of the
cooling water, the heating power, pressure and temperatures at all relevant points. The
measured values can be read on digital displays
