Final Report Abstract
The central role of gaseous fuels in today’s electricity and heat production motivated to obtain a better understanding of the detailed chemical pathways governing the combustion of these fuels. While very small gaseous fuels have been intensely studied, the combustion of medium to large gaseous fuels could not be predicted sufficiently accurate. This research therefore aimed at providing experimental insights into the reactivity and chemical intermediates of these gaseous fuels. The detailed combustion chemistry of n-propane, n-butane, and unsaturated versions of these gaseous fuels has been studied by different experimental facilities which allowed to achieve application-relevant high-pressure conditions. Gas was extracted from these facilities at different times prior to ignition and was analyzed to better understand the formation and consumption of intermediates. With the help of all these experiments, existing models were tested and improved to achieve a better representation of the ignition process. The models developed have greatly improved the accuracy of the description of the combustion processes of gaseous fuels, aiding, for example, the modelling of gas turbines. In addition, a more holistic understanding of gaseous fuels facilitates the formulation of synthetic alternatives, potentially reducing the carbon footprint of current power and heat generation.
