MECH ENG 4112 - Combustion Technology & Emission Control

North Terrace Campus - Semester 1 - 2015

The course covers the basis of thermal energy technologies that are common not only to combustion, but also to high temperature solar thermal production of fuels and commodities. The transition of our energy systems from their present 80% reliance on fossil fuels to increasing fractions of renewable energy including biomass, waste and concentrating 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 understand, 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 and safety.

  • Learning & Teaching Activities
    Learning & Teaching Modes

    The course is heavily biased toward practical tools, with 15 hours of tutorials, 6 hours of laboratory work and a 2 hour tour, compared with 21 hours of lectures. It is centred around a Design Project, which designs the combustion system for a rotary cement kiln and includes undertaking a mass and enegy balances to size the burner and a momentum-based mixing parameter. The tour is of a large and leading cement plant 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. The virtual combustion laboratory is a unique learning tool developed by the lecturing staff, in which the user can assess the effect on the performance of a flame of varying the fuel flow rate based on real-flame data recorded in our laboratories and presented in an interactive format. This is linked to the lectures on premixed and non-premixed flames.

    In addition to the marked assignments, three other 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. The virtual combustion laboratory can be completed in the allocated time provided students are well organised and focussed on the task. 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.

    Learning Activities Summary

    No information currently available.

    Specific Course Requirements

    Long-sleeves, long pants and closed toe shoes are a requirement for the industrial tour. Students should be aware that they will be walking through a dusty plant, so that strong work-shoes or work-boots are recommended and one should avoid wearing “best” white or polished shoes if you want them to remain in their original state.

    Buses will be provided and students must nominate for the early or late time option. Details will be provided in the lectures.

  • 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.

    Assessment Summary

  • 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.
