MECH ENG 4112 - Combustion Technologies & High Temperature Processes

North Terrace Campus - Semester 1 - 2024

The course covers the basics of thermal energy technologies that are common for combustion and fuels, with an emphasis on high temperature production processes. The Paris Agreement requires elimination of global, energy-based greenhouse gas (GHG) emissions by 2050, and this will demand a staggering transformation since 80% of current energy systems rely on the combustion of fossil fuels. This move to increasing fractions of renewable energy, including renewable hydrogen, biomass, waste and concentrated solar thermal, is driven by the need to mitigate GHG emissions and is expected to take around 50 years. The deployment of carbon capture, utilisation and storage (CCUS) technology alongside existing fossil fuel energy production is also expected. Managing these changes brings many technical challenges, since any change in fuel composition or energy mix will influence the design of the combustion system, fuel consumption and pollutant emissions. The course will equip participants with the knowledge and skills necessary to address these challenges. It covers the understanding, analysis and design of modern combustion systems to account for fuel properties, maximise output and minimise air pollution. Combustion involves both mixing of the fuel and oxidant and the subsequent chemical reactions. The course therefore involves consideration of both combustion aerodynamics and fuel properties. It covers fuel selection, alternative and waste fuels, the design principles involved in reducing pollutant emissions, modelling, applications of combustion for power generation and minerals processing, hybridising combustion with concentrated solar thermal energy and fuel upgrading using solar thermal energy.

    Recommended Resources

    The following texts are highly relevant and strongly recommended, but are not followed directly:

    S.R. Turns “An Introduction to Combustion”, McGraw Hill,

    PJ Mullinger and B.G. Jenkins “Design and Operation of Industrial and Process Furnaces”, Elsevier (This book is available as an e-book, via the Barr Smith library, for students enrolled at the University of Adelaide. 

    Online Learning

    Lectures are provided online with the lecture slides available in MyUni

    Supplementary material for the design project will be provided in MyUni

    A range of other learning materials is available via MyUni

  • Learning & Teaching Activities
    Learning & Teaching Modes

    The course is biased toward practical problem solving, with 4 hours of problem solving and design project workshops in most weeks. The course is centred around a group-based Design Project, which has the objective of designing the combustion system for a rotary cement or lime kiln and includes mass and enegy balances to size the kiln, heat transfer calculations to estimate kiln temperature and heat losses and momentum-based mixing calculations to size the burner. The lectures are pre-recorded, provided weekly via Echo360 / MyUni, and are structured to provide relevant input to the design process.

    Workload

    The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

    The design project is undertaken in groups of four for all students, however the project for postgraduate students includes a more expansive scope and is more challenging. The project is a significant undertaking, but can be readily managed by working steadily as a group through the entire semester, attending the weekly Design Workshops and following guidance provided during these workshops. There are two progress reports, with oral presentations, which provides feedback for groups to ensure they remain on track. Students should allow about 2 hours per week to review the pre-recorded lecture content and also prioritise attendance at problem-solving workshops each week.

    Learning Activities Summary
    The following topics will be covered in the pre-recorded lectures:

    Topic 1: Significance, Applications and Process Efficiency
    Topic 2: Stoichiometry and Thermochemistry
    Topic 3: Fuels and Fuels Handling
    Topic 4: Flames and Burners, including Hydrogen Safety
    Topic 5: Heterogeneous Combustion
    Topic 6: Combustion Safety
    Topic 7: Combustion-generated Pollutants
    Topic 8: Solar Thermal Technologies

    Weekly workshops (formative) will apply this theory through solving problems exercises associated with each of the topics.

    The kiln design project runs in parallel with these topics and is supported by dedicated weekly Design Project workshops.
  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

  • Student Feedback

    The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

    SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
