Product Code : SCL-CELE-13931
The unit is a self-contained system built on an anodized
aluminum structure with a diagram on the front panel illustrating the process
flow.
1. Water Boiler and Steam Generation
- Boiler:
Includes a sight glass for level control and observing boiling patterns.2
- Heating
Element: Computer-controlled immersion heater with a power of 1000
W.
- Pressure
Limit: Equipped with a safety valve to limit the
working pressure to 8 bars and a high-pressure switch for additional
safety.3
2. Throttling Calorimeter
- Function: The
saturated steam generated in the boiler is passed through a throttling
valve and expanded to atmospheric pressure in the calorimeter.
- Purpose: The
expansion process (throttling) is used to convert the wet steam into
superheated steam (if the initial quality is high enough), allowing for
the determination of the initial dryness fraction (steam quality).

Core Experiment Capabilities
The unit supports crucial experiments in thermodynamics,
focusing on saturated states and steam properties.
1. Saturation Loop / P-T Relationship
- Saturation
Curve: Measures the relationship between temperature and
pressure of the saturated vapor over the range of 0 to 8 bar gauge.
- Analysis:
Allows students to understand the origin and use of steam tables,
compare experimental data to published saturation curves, determine the
describing equation, and calculate the percentage of error between
experimental and theoretical data.
- Concepts: Study
of the saturation line, two-phase fluid characteristics, and the
difference between gauge and absolute pressures.4
2. Throttling Calorimeter
- Steam
Quality: The primary use is the determination of the dryness
fraction (quality of the steam) produced by the unit at different
operating pressures.
- Thermodynamics:
Requires the application of the steady flow energy equation and
understanding the concept of the enthalpy of vaporization (the
difference in enthalpy between phases).
Control and Safety
- The
unit is protected by transparent methacrylate sheets.
- It
includes a high-pressure switch and a safety valve.5
- The
unit can be optionally supplied with a Computer Control System (DAQ),
enabling data logging, real-time control, sensor calibration, and applied
research.6
