SL220 Boiling Process Vocational Education Equipment For School Lab Heat Transfer Demonstrational Equipment 1. Description
Heating, a limitation of the heat flux density must be assured In order to prevent damage to the heating surface. This knoSLedge is applied in practice eg when designing steam boilers for steam-powered drives.
The volt 220 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.
Rap3.com is used as evaporating liquid.
Sensors record the flow rate of the cooling water, the heating power, pressure and temperatures at all relevant points.
