Item 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.
Sci-tech Boiling Process Model TH 071 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. Compared with water,
this liquid has the advantage that its boiling point is at 36,7°C (1013hPa), whereby the evaporation process
takes place at much lower temperatures and a lower heating power.
