Steam Boiler and Turbo-Alternator Trainer
Description: The Steam Power Generation / Thermodynamics Trainer consisting of a pressure boiler, non-condensing steam turbine, alternator, load and control system. A number of options are available which will enhance the features and learning objectives.
Training Topic:
- Pressure boilers
- Steam turbine/alternators and controls
- Thermodynamics
Sub Topics: (dependent upon options chosen)
- Boiler operation and controls
- Turbine/alternator operation
- Combustion reaction chemistry
- Efficiency calculations
Key Learning Objectives: Trainees will demonstrate an understanding of (dependent upon options chosen):
- Pressure boiler start-up and operation
- Steam turbine start-up and operation
- Alternator and power switching controls
- Impact of load on operation
- Combustion reaction chemistry and excess oxygen
- Turbine/alternator conversion efficiency
- Thermal vs. mechanical vs. electrical efficiencies
System Capacity: nominal electrical output of 30 kW
Options include:
Fuel: Natural gas, LPG or liquid fuel (please specify)
Steam Cycle Configuration Options:
- Open Cycle – low pressure (LP) steam vented, condensate returned to feed water boiler feed water (BFW)
- Closed cycle with chilled water condenser – LP steam condensed for recycle to BFW
- Closed cycle with aerial atmospheric condenser – LP steam condensed for recycle to BFW
Power and Load Configuration Options:
- Induction Generator – Power to grid with minimal controls (grid excited)
- Synchronous Generator / resistive load – Stand-alone system with power dumped to air cooled resister bank
- Synchronous Generator / grid connected – Power to grid with phasing & synchronization controls
