MECH ENG 4112 - Combustion Technology & Emission Control

North Terrace Campus - Semester 1 - 2019

The course covers the basis of thermal energy technologies that are common for combustion and fuels. The transition of our energy systems from their present 80% reliance on fossil fuels to increasing fractions of renewable energy including biomass, waste and concentrated solar thermal, is driven by the need to mitigate CO2 emissions and is expected to take around 50 years. Managing this change 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 the participant 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 principals involved in reducing pollutant emissions, modelling, applications of combustion for power generation and minerals processing, and hybridising combustion with concentrated solar thermal.

  • Learning & Teaching Activities
    Learning & Teaching Modes

    The course is heavily biased toward practical problem solving, with 4 hours per week of normal tutorials and design project tutorials, compared with 2 hours per week of lectures. It is centred around a Design Project, which has the objective of designing the combustion system for a rotary cement kiln and includes  mass and enegy balances to size the kiln and momentum-based mixing calculations to size the burner. If available, a plant tour of a large and leading cement plant is undertaken, to provide insight into the facility being designed by students in the classroom. The lectures are structured to provide relevant input to the design process. In addition to the marked assignments, progress reports and final report for the design project, many other in-class tutorials are provided that are not examined.

    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 Final Year students, and individually for Masters students. It is a significant undertaking, but can be readily managed by working steadily through the semester. In addition, two assignments are given during the early sections of the course. The work-load has been refined over the ten years in which the course has been run to provide a balanced work-load that is well reflected in the value of the 3 point subject.

  • 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.
