The project involves a laboratory experimental study to examine the mechanisms of ultra-lean combustion, coupled with a computational fluid dynamics (CFD) and kinetic modelling study to investigate scale-up parameters.
Coal mine ventilation air (MVA) emissions are characterised by very low methane concentrations (typically less than 1%), high flow rates (up to 1900 m3/s) and significant short and long term fluctuations in both concentration and flow. These attributes constitute the major technical barriers to the capture and use of the methane in MVA. A cost effective method of MVA mitigation, which does not require either a supplementary fuel source or a large-scale infrastructure for power generation, has yet to be proven.To address this challenge the Laboratory for Sustainable Technology is developing a novel porous burner reactor using advanced computational modelling techniques. Porous burners have the ability to burn lean fuel/air mixtures, and it has additionally been shown that the combustion process is stable against changes in fuel concentration and flow rate.
