Alternative fuels are playing an increasingly important role in power supply. These fuels can be extracted, for example, from the gasification of biomass or coal. They are characterised by high concentration of H2 and CO and have different combustion characteristics in comparison to natural gas, e.g. other combustion temperatures, flame speeds or ignition delays. Before these synthetic fuels can be used in industrial gas turbines, it is therefore necessary to study their basic combustion characteristics.

At the Institute, gas turbine-specific flames are operated with a variety of synthetic gas mixtures and analysed using laser-based measurement techniques. Special interest is focused on flame stability, thermoacoustic oscillations and pollutant emissions.
