CHEM ENG 4046 - Combustion Processes

North Terrace Campus - Semester 1 - 2020

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 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.

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.

This assessment breakdown complies with the University's Assessment for Coursework Programs Policy.

Due 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.

To support the changes to teaching, the following revisions to assessment have been made:-
A shorter open-book online quiz (worth 25%) will replace the 3-hr invigilated open-book exam (worth 60%). I expect
the online quiz to be held during the scheduled exam period in Semester 1. More details will be provided later.

The Kiln Design Project (40%) will be given a higher weighting of the overall course assessment (increased from 30%). We will be using peer- and self-assessment to ensure that contributions by all students are appropriately accounted for in the final marks awarded for this assessment task.

The individual design project reports will have weighting as follows:
Progress Report 1 (due Week 6) = 5% (unchanged)
Progress Report 2 (due Week 8) = 10% (increased from 5%)
Final Report 3 (due Week 13) = 25% (increased from 20%)
The number of class assignments (35%) will be increased from two to four with the total weighting increased accordingly (from 10%). By increasing the weighting and workload associated with this component of the overall assessment we seek to ensure that students remain fully engaged with the course content throughout the semester while reducing the emphasis on the end-of-semester exam.

The new assignment schedule will be as follows:
Assignment 1: Stoichiometry & Thermochemistry (Prof Ashman) - due Week 5 (5%)
Assignment 2: Fuels & Combustion Safety (Dr Smith) - due Week 7 (10%)
Assignment 3: Flames & Heterogeneous Combustion (Dr Chinnici) - due Week 10 (10%)
Assignment 4: Solar Technologies (Dr Jafarian) - due Week 12 (10%)

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.

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鈥檚 disciplinary procedures.
