Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. Thi ....Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. This information will be input to comminution and wear models to predict pulveriser performance and wear patterns. Simulation results will be validated using measurements from scale visualisation and working models.Read moreRead less
Advanced signal processing techniques to improve prognostic models for rolling element bearings. Novel signal processing techniques for predicting the development of faults in rolling element bearings will be developed and employed in a statistical prognostic model. This will greatly improve the economics of operation of many different machines, including helicopters and other aircraft, mining machinery, and wind turbines.
Chemical optimisation of geothermal heat extraction. Geothermal energy can contribute to our energy needs, but we must understand chemical interactions between geothermal fluids, the host aquifers and the engineered environment to use the energy safely and efficiently. This project will assess those interactions, provide guidelines for geothermal energy use and train future geothermal scientists.
Enhanced carbon removal in secondary steel refining. The purpose of this project is to develop effective methodologies to increase the decarburisation rate in the vacuum degassing process which is used for the production of high value added steel products at BlueScope Steel. It is expected that the project outcomes will result in improved quality and productivity of the high value added steel products.
Phosphorous and iron recovery from steelmaking slag for effective recycling. This project aims to understand the principles that control phosphorus (P) partitioning in steel plant slags and to optimise the treatment process to produce P- and Fe-rich streams for recycling. Changing ore grades in Australia, especially increasing P content, are placing a substantial proportion of these ore products at a competitive disadvantage. The project will use an integrated approach to demonstrate, experiment ....Phosphorous and iron recovery from steelmaking slag for effective recycling. This project aims to understand the principles that control phosphorus (P) partitioning in steel plant slags and to optimise the treatment process to produce P- and Fe-rich streams for recycling. Changing ore grades in Australia, especially increasing P content, are placing a substantial proportion of these ore products at a competitive disadvantage. The project will use an integrated approach to demonstrate, experimentally and theoretically, how key properties of slags can be manipulated to enhance partitioning and couple this analysis with fluid dynamics to model the kinetics of the separation process. The expected outcomes of this research are to: first, provide possible solutions to address the increasing P content in Australian iron ores, which could place future ore products at a competitive disadvantage within the global iron ore market; and second, to identify treatment methods and practices which would promote higher recycling rates of steelmaking slag, significantly reducing the volume of material stockpiled or sent to landfill.Read moreRead less

This project will research the surface burning process of AN prills and other materials to understand possible NOx production and mitigation pathways. The results from the project are expected to overcome the limitations of the new technology, and make Australian industries more competitive.Read moreRead less
Advanced environmental technologies for increasing coal seam permeability. This project aims to understand the physical/chemical mechanisms occurring when benign chemicals interact and dissolve minerals and coal surfaces in the natural fractures during the extraction of coal seam gas. Technologies for increasing the permeability of coal have become necessary for commercially viable coal seam gas (CSG) extraction in Australia. Currently available methods from the conventional gas industry, are pr ....Advanced environmental technologies for increasing coal seam permeability. This project aims to understand the physical/chemical mechanisms occurring when benign chemicals interact and dissolve minerals and coal surfaces in the natural fractures during the extraction of coal seam gas. Technologies for increasing the permeability of coal have become necessary for commercially viable coal seam gas (CSG) extraction in Australia. Currently available methods from the conventional gas industry, are problematic for coal, and fail to capitalise on coal’s existing fracture network. The intended project outcome is a range of new coal-specific technologies for enhancing permeability that avoid unwanted and irreversible damage to seams and protect the environment. Combined with reduced costs, these methods would benefit sustainable growth of Australia’s CSG industry.Read moreRead less
Mitigation of nitrogen oxides (NOx) formed in blasting of ammonium nitrate explosives. Several mines in Australia experience the formation of orange-brown fumes containing nitrogen oxide (NOx) gases, immediately after blasting of ammonium nitrate (AN) explosives to crush the rock. This project develops new explosives technologies, aimed to mitigate the formation of post-blast fumes, that are safe to people and the environment.

Enhancing the position of Australian iron ore exports through understanding and altering the coalescence phenomenon during sintering. The revenue from Australia's iron ore exports is currently worth over US$50 billion. Current and future changes in iron ore properties means that sinter plants have to use more low bulk density ores. This results in deterioration in sinter properties. This project is aimed at developing technologies to maintain sinter strength and size.
