Future Fuels - alternative Fuels
Alternative fuels are of primary importance for securing a climate-friendly energy supply and mobility. In our institute, technologies and design tools are developed for a clean and efficient use of liquid and gaseous alternative fuels in gas turbine combustors.
Burners for Gas Turbines
Development of fuel-flexible low-emission combustors for gas turbines based on the FLOX
-concept of intense mixing of fuel, air and burned gas
Unsteady Combustion Processes
Gas turbine combustors are affected by a variety of unsteady combustion phenomena including igni-tion (auto ignition or external ignition) and extinction, flame stabilization, thermo-acoustic pulsation and fluid-dynamic instabilities. These processes are characterized by a strong interaction between the flow field and the chemical reactions. Due to their strong dynamics, unsteady combustion processes present a major challenge for both numerical simulations and experimental investigations.
Micro Gas Turbine-based Power Plants
Research activities in the field of power plant concepts are focused on the development, design and optimisation of low-emission, fuel-flexible and highly efficient power plant concepts based on MGTs. Both conventional and innovative power plant concepts are considered. The areas of application are the fields of energy, transport and aviation with electrical output ranging from one kilowatt to several hundred kilowatts.
Within the European project FIRST (Fuel Injector Research for Sustainable Transport, FP7/n265848) a comprehensive data set for validation of complex soot models was generated. Several laser-based diagnostics were applied to a dual swirl burner at increased pressure, operated with ethylene as fuel. The data set is used to validate the complex soot model which is implemented in the DLR code THETA.
