Separating and Throttling Calorimeter

The set up consists of a separating and throttling calorimeter. A steam generator is provided at the base of the apparatus. A digital temperature controller is provided to control the temperature inside the steam generator. Steam from steam generator is passed from separating calorimeter where most of the water particles get separated from steam and then passed to throttling calorimeter where steam get superheated. After that, superheated steam is passed through heat exchanger to condense the steam. A manometer and a thermometer are connected with throttling calorimeter to measure the pressure and temperature after throttling process.

Separating Calorimeter It consists of two concentric chambers, the inner chamber, and the outer chamber, which communicates with each other through an opening at the top.  As the steam discharges through the metal basket, which has a large number of holes, the water particles due to their heavier momentum get separated from the steam and collect in the chamber. The comparatively dry steam in the inner chamber moves up and then down aging through the annular space between the two chambers and enters the Throttling Calorimeter.

Throttling Calorimeter It consists a narrow throat (Orifice). Pressure and temperature are measured by manometer and thermometer.  The steam after throttling process passes through the condenser and condensate is collected.
