Steam Turbine

Steam Turbine

A mobile, laboratory-scale steam plant for experiments in thermodynamic principles. It helps students to understand:

• Thermodynamic laws of energy conservation

• Steady flow energy equation

• Thermal efficiency

• Rankine cycle analysis

A mobile frame contains all the parts of the test set. A variable-speed, low-voltage piston pump takes water from the reservoir and feeds it into a flash boiler. The thermostatically controlled flash boiler, which is electrically powered (no gas required), has a pressure-relief and thermal trip (200°C) fitted. Steam from the boiler moves up to and expands through the single stage, Ø127 mm axial turbine powering the electric dynamometer. The load applied by the dynamometer can be varied via the control panel. Optionally, the power generated may be used to power a 12 V device (e.g. laptop).

The used steam is condensed through the steam-to-air heat exchanger. Cooling fans can be activated to control the temperature of the return water to reservoir closing the cycle. Preheated feedwater increases the machine’s efficiency.

For quicker tests with easier recording of results, the steam turbine comes with TecQuipment’s Versatile Data Acquisition System (VDAS®) Onboard. The software is free to download from TecQuipment’s website. This system provides accurate real-time data capture, monitoring and display, calculation and charting of all the important readings on a computer.
