Our goal here is to acquire fundamental knowledge about the redox behaviour of metal oxide oxygen carriers which, arguably, underpins the feasibility of the Chemical Looping Combustion (CLC) concept. Although the proposed work is fundamental and will contribute to the advancement of knowledge, the results will have immediate practical applications in power generation industry at both national and international levels. This should significantly contribute to the Australian Government's efforts in producing world class solutions for abatement of greenhouse emissions (Research Priority 1: An Environmentally Sustainable Australia, Priority Goal 1.4 - Reducing and capturing emissions in transport and energy generation).Read moreRead less
Development of a gas-diesel engine injection system using a hydraulically actuated, electronically controlled unit injector (HEUI) for flexible dual-fuel operation. Achieving targets for greenhouse gas reduction will require practical, easily implemented alternative fuels for vehicles. Converting existing truck/bus diesel engines to dual-fuel systems using natural gas is important. In particular, for long distance application, these systems need to allow flexible switching from sole diesel to du ....Development of a gas-diesel engine injection system using a hydraulically actuated, electronically controlled unit injector (HEUI) for flexible dual-fuel operation. Achieving targets for greenhouse gas reduction will require practical, easily implemented alternative fuels for vehicles. Converting existing truck/bus diesel engines to dual-fuel systems using natural gas is important. In particular, for long distance application, these systems need to allow flexible switching from sole diesel to dual-fuel operation and good gas substitution at low loads within cities. An earlier ARC funded project allowed UNSW to develop the world's most compact, flexible HEUI diesel injector. This project aims to develop, test and explore dual-fuel combustion using a compact single unit, combined NG/HEUI injector which will have considerable combustion and operational advantages.Read moreRead less

Summary
Advanced Laser Diagnostics in Dilute Heterogeneous Combustion. This proposal seeks to establish a state-of-the-art laser diagnostics facility with unique capabilities for non-intrusive measurements in dilute multi-phase flows. Such heterogeneous flows which involve stationary surfaces, disperse suspended droplets or suspended particles are found in many applications including engines, furnaces, industrial and chemical processing and micro-combustion devices.

This proposal seeks to establish a state-of-the-art laser diagnostics facility with unique capabilities for non-intrusive measurements in dilute multi-phase flows. Such heterogeneous flows which involve stationary surfaces, disperse suspended droplets or suspended particles are found in many applications including engines, furnaces, industrial and chemical processing and micro-combustion devices. This facility will give Australian researchers the unprecedented opportunity to perform measurements of flow, mixing, temperature and composition fields in the gas and liquid or solid phases simultaneously. The resulting data will advance current knowledge in these complex flows and lead to new and improved reactor designs.

The Effects of Pyrolysis Conditions on Combustion and Gasification Reactivities of Biomass Chars and the Quality of Their Ash. Considerable efforts are being made to minimise the environmental impacts of fossil fuels by utilising renewable energy sources like biomass.

Considerable efforts are being made to minimise the environmental impacts of fossil fuels by utilising renewable energy sources like biomass. Many of the challenges associated with the thermal conversion of biomass relate to its char characteristics. The aim of this project is to gain a fundamental understanding about the impact of reaction conditions during the pyrolytic stage on the structural and compositional transformations of the resultant char, its combustion and gasification reactivities, and the release of inorganic matter and ash formation. This holistic and integrated approach should reveal the underlying science necessary to support existing and future biomass use.Read moreRead less
Enabling low greenhouse gas emissions from road vehicles through the proper use of alternative fuels. A major increase in alternative transport fuel use appears necessary in our response to the challenges of climate change and energy security. This proposal will advance our fundamental understanding of key aspects of the combustion of particular alternative fuels, thus enabling proper engine design and so maximising greenhouse and energy security benefits. Further, the Australian automotive indu ....Enabling low greenhouse gas emissions from road vehicles through the proper use of alternative fuels. A major increase in alternative transport fuel use appears necessary in our response to the challenges of climate change and energy security. This proposal will advance our fundamental understanding of key aspects of the combustion of particular alternative fuels, thus enabling proper engine design and so maximising greenhouse and energy security benefits. Further, the Australian automotive industry is a major employer and exporter, and needs to develop and/or maintain international leadership in low emission technologies to ensure its long term viability. This proposal builds a consortium of local organisations with common interests, thus helping local industry respond to several, significant challenges that they presently face.Read moreRead less
Quantification of heat release, NOx emissions and soot from high temperature gaseous flames. The ongoing importance of Australia's minerals processing sector depends on advanced combustion technology to minimise the emission of NOx and other greenhouse gases. The heat release and NOx emissions from the high temperature flames used in such processes is known to depend strongly on the presence of soot. However their optimisation and design is limited by a lack of fundamental data under relevant c ....Quantification of heat release, NOx emissions and soot from high temperature gaseous flames. The ongoing importance of Australia's minerals processing sector depends on advanced combustion technology to minimise the emission of NOx and other greenhouse gases. The heat release and NOx emissions from the high temperature flames used in such processes is known to depend strongly on the presence of soot. However their optimisation and design is limited by a lack of fundamental data under relevant conditions. To address this need, new measurements and analysis will be performed to quantify the complex relationship between turbulent mixing, soot formation, heat release and NOx emissions under high temperature conditions of both fundamental and practical significance.

Summary
Integrated Combustion Research Facility for Biomass Derived Fuels. Bio-mass derived fuels are gaining in importance because they can contribute to solving the problems arising from the world wide decline in the reserve to production ratio of crude oil, the emission of greenhouse gases and energy security. In Australia they can also assist in mitigating dry-land salinity by increasing the viability of large-scale plantation of locally indigenous trees. However significant technical and political ....Integrated Combustion Research Facility for Biomass Derived Fuels. Bio-mass derived fuels are gaining in importance because they can contribute to solving the problems arising from the world wide decline in the reserve to production ratio of crude oil, the emission of greenhouse gases and energy security. In Australia they can also assist in mitigating dry-land salinity by increasing the viability of large-scale plantation of locally indigenous trees. However significant technical and political issues remain to be addressed before this potential can be realised. The Integrated Combustion Research Facility for Biomass Derived Fuels to be established by this grant will provide the necessary infrastructure to address these issues.Read moreRead less

This project seeks to revolutionize the way bulk chemicals are made industrially. By combining highly integrated process designs, with profound process intensification, we will create the basis for chemical process technology that is efficient and economical at relatively small scale. This development will reinvigorate the Australian chemical industry, with enormous benefits to the country in terms of improved security of supply of chemicals and fuels and reduced trade deficit. This new type of plant will be scaleable and without the technical risk normally associated with plant scale-up. At the smallest scale, it will be mobile and able to utilise remote and dispersed feedstocks such as stranded natural gas, coal bed methane, or biogas. Read moreRead less
