The furnace grate is a key component of the many boilers that burn solid fuels. Many biomasses with large particle sizes such as woodchip burn on furnace grates and grate combustion assists the combustion of fuels that burn in mostly in suspension such as sugar cane bagasse and sawdust.
While furnace grates are successfully used in the combustion of a range of solid fuels, they can overheat and fail, resulting in downtime and high costs for grate replacement.
This project will used computational fluid dynamics (CFD) simulations to study the radiation and convection heat transfer processes that are present in the furnaces of solid fuel boilers. Grate temperatures will be predicted for various furnace fuel firing configurations and grate designs using CFD.
The required hardware and software are available from QUT High Performance Computing (HPC at eResearch).
The project will improve the understanding of grate heating mechanisms and help determine grate designs and/or design modifications that reduce the chance of overheating and enhance combustion and heat transfer.
You will gain skills in CFD modelling and boiler design, aided by supervision, assistance and feedback from researchers with a strong emphasis on delivery to industry.
Skills and experience
You will have a keen interest in understanding combustion engineering processes and prior skills and experience in CFD.
