Fundamental Fire Properties From Extinction and Piloted Ignition Experiments of Solid Fuels. Current approval methods for determining fire properties of construction materials are often incorrect in yielding properties that can be used in situations removed from test conditions. The main aim of this project is to obtain fundamental fire properties by examining the ignition and extinction processes of diffusion flames near solid surfaces. The project undertakes detailed study of flame spread in ....Fundamental Fire Properties From Extinction and Piloted Ignition Experiments of Solid Fuels. Current approval methods for determining fire properties of construction materials are often incorrect in yielding properties that can be used in situations removed from test conditions. The main aim of this project is to obtain fundamental fire properties by examining the ignition and extinction processes of diffusion flames near solid surfaces. The project undertakes detailed study of flame spread in the direction opposite to the flow of air, which defines the initial fire growth and is important in fire propagation. Results from this project will provide scientific underpinning for the development of approval standards for new materials, which are needed to support Australia's transition from prescriptive to performance based building codes.Read moreRead less

Summary
Facility for Analysis of Thermal Decomposition of Solid Materials at High Pressures. This submission aims to establish an integrated facility for studying the kinetics of solid and gas-solid reactions at elevated temperatures and high pressures; a piece of infrastructure that is urgently needed in Australia.

This submission aims to establish an integrated facility for studying the kinetics of solid and gas-solid reactions at elevated temperatures and high pressures; a piece of infrastructure that is urgently needed in Australia. The facility will consist of a high-pressure thermal gravimetric analyser (TGA) able to operate at up to 5 MPa, which will be coupled to a mass spectrometer (MS) for identification and quantification of gaseous reaction products. The facility constitutes unique and significant national research infrastructure for the simultaneous acquisition of mass loss kinetic measurements together with characterisation and quantification of emission rates of gaseous fragments generated in the reaction. As a major outcome, the facility will provide a means for consistent investigation of kinetics of elemental reactions occurring in solids, or on solid surfaces during pyrolysis and gasification processes at high pressure.Read moreRead less
Bio-oil from woody biomass - a sustainable fuel for Australia. At present many alternative energy supply systems suffer from factors like high costs, inefficiency and in some cases inappropriate application of immature technology and so are unsustainable. To overcome these problems, this research proposes the development of an integrated biomass solution to energy supply as well as dry land salinity. By doing so a sustainable and cost effective industry can be developed. Furthermore, if such an ....Bio-oil from woody biomass - a sustainable fuel for Australia.

To overcome these problems, this research proposes the development of an integrated biomass solution to energy supply as well as dry land salinity. By doing so a sustainable and cost effective industry can be developed. Furthermore, if such an industry is based on advances in Australian research and development, exporting this to other countries with similar problems, will further enhance its economic and social benefit to Australia.Read moreRead less

Assessment of the aerodynamic behaviour of fibrous particles under well-defined conditions of relevance to bio-fuel combustion. Biomass is plant-derived fuel, which has the advantage of being greenhouse neutral. Biomass can potentially be utilised both in existing combustion technologies, after minor modifications, and in purpose-designed combustors. It is typically fed into a furnace or boiler as shredded particles, (e.g. of wood, straw or bagasse), with jet(s) of air, either alone or as part ....Assessment of the aerodynamic behaviour of fibrous particles under well-defined conditions of relevance to bio-fuel combustion. Biomass is plant-derived fuel, which has the advantage of being greenhouse neutral. Biomass can potentially be utilised both in existing combustion technologies, after minor modifications, and in purpose-designed combustors. It is typically fed into a furnace or boiler as shredded particles, (e.g. of wood, straw or bagasse), with jet(s) of air, either alone or as partial replacement of pulverised coal. However these particles are fibrous and, unlike round particles, their aerodynamic behaviour in such systems is poorly understood. The project will provide new understanding, data and models necessary to maximise efficiency and minimise emissions from the utilisation of these fuels.Read moreRead less

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.

This design is expected to overcome the high pressure drop of the present design which limits its range of application. The program will apply advanced measurement techniques to study the aerodynamic behaviour of particles, which control many aspects of the combustion. These will be used to advance understanding and for the development and validation of computational fluid dynamics (CFD) models. A preferred design will be assessed in FCT's model lab and then in full-scale trials.Read moreRead less

Wide spread substitution of liquid hydrocarbon fuels by indigenous renewable bio-oil has the potential to improve Australian's energy outlook and assist in reaching greenhouse gas targets. Understanding the interrelationships between the physical and chemical properties of bio-oil, its atomisation, droplet formation and combustion physics is fundamental to the delivery of an efficient and reliable combustion process using this fuel.
