Bio-diesels and bio-alcohols have emerged as attractive renewable alternate energy sources in recent years. These fuels can be produced from vegetal or animal feed stocks, they are environmentally carbon-neutral, and are low in sulfur content. In many places, they can be produced from locally-grown or otherwise wasted biomass, and thus ensure energy security. Also, these biofuels can be directly used in existing combustors with minimal modifications. The key to the successful use and consumer acceptance of these biofuels is to ensure that their environmental impact is minimal and that their performance in practical combustion devices is favorable. Although the performance of practical devices such as internal combustion engines and gas turbines running on these fuels has been extensively investigated in the past by several researchers, a fundamental understanding of the science of thermo-chemical processes and pollutant formation during the combustion of biofuels and their blends, particularly the coupling effects of fuel chemistry and combustion conditions is lacking. This presentation will cover an integrative approach of a comprehensive research program with a focus on the work currently being pursued at the Combustion and Flame Dynamics Laboratory of the University of Oklahoma, USA. Results include thermochemical characteristics, such as temperature and concentration fields, radiation emission and extinction phenomena, and formation of environmental pollutants such as NO and CO. The flames will include laminar and turbulent jet configurations and counter-flow burners.
