MECH ENG 7021 - Combustion Technologies & High Temperature Processes
North Terrace Campus - Semester 1 - 2023
General Course Information
Course Code MECH ENG 7021 Course Combustion Technologies & High Temperature Processes Coordinating Unit School of Mechanical Engineering Term Semester 1 Level Postgraduate Coursework Location/s North Terrace Campus Units 3 Contact Up to 6 hours per week Available for Study Abroad and Exchange Y Course Description 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.

Course Learning OutcomesOn successful completion of this course students will be able to:
1 Recognise the ongoing role of combustion, both of fossil and bio-fuels, in providing a more sustainable energy source for society, and the environmental challenges to be met to achieve this; 2 Apply the principles of combustion; 3 Explain the complexities of industrial combustion processes; 4 Summarise the mechanisms of combustion generated air pollution and the techniques that can be used to control them; 5 Summarise the complementary roles of measurements, modelling and scaling in understanding combustion, and in solving industrial problems; 6 Summarise the safety and handling issues associated with combustion; 7 Outline the impact of different fuel properties on industrial combustion systems; 8 Outline the potential of combining combustion and solar thermal technologies as a route towards sustainable energy production

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.
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

The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment SummaryDue to the current COVID-19 situation modified arrangements have been made to assessments to facilitate remote learning and teaching. Assessment details provided here reflect recent updates.

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.

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.
