Thermal power and systems enables students to acquire basic knowledge on traditional and non-traditional power plants. Students will gain knowledge on various types of power plants, such as steam, gas turbines, IC engines and hydropower plants. Students will acquire knowledge on power plant components. They will be aware of source of primary energy requirements of power plants such as; fossil (solid, liquid and gaseous fuels), nuclear, renewable/sustainable sources (solar, wind, tidal, geothermal, biomass, biogas). They will be aware of relative advantages of various power plant systems, fuel requirements, environmental pollution and carbon capture methods.

Subject Topics

1.       Introduction and economics of power generation

2.       Steam Power Plants-Traditional and Non-Traditional Power Plants

3.       Gas Turbines

4.       IC Engine Power Plants

5.       Hydropower Plants and Components

Subject Learning Outcomes (SLOs)

On completion of this subject students will be able to:

  1. Discuss economics of power plants
  2. Solve problems which require them to apply laws of thermodynamics on various power plant systems
  3. Design and recommend improvements for conventional power plants and their components. Conduct team investigations on the feasibility of renewable energy design systems that meet specific energy demands and minimal environmental impact requirements;
  4. Describe fuel requirements for different systems
  5. Reflect on the importance of environmental pollution, protocols on controlling pollutions
  6. Working in teams to undertake laboratory exercises, analyzing and discussing the outcomes and communicate those via professional reports.

Assessment Tasks and Weightings

To obtain a pass grade in this Subject at least 50% overall must be achieved, and at least 40% achieved in the final examination. Students must also refer to the Subject Assessment Details.

Assessment 1 – Lab/Project Concept Report: A team based or individual component report outlining individual or team formation. Team based report outlining formation and member roles, project selection, team and member action plan and a schedule of future activities to achieve the outcome. The report contributes 20% towards the final grade for the subject.

Assessment 2 – Assignments: The assignments are intended to support students achieving the learning outcomes for the Subject and will contribute 20% towards the final grade for the subject.

Assessment 3 – Class Test: The Test contributes 20% towards the final grade for the subject and evaluates progress towards achievement of learning outcomes.

Assessment 4 – Final Examination (E): The individual components of final examination enable final evaluation of achievement of learning outcomes and contribute 40% towards the final grade for the subject

It is important that all students familiarise themselves with the University of Technology Assessment Guidelines including those on plagiarism in the Academic Integrity Policy at:
