DLR site Stuttgart

DLR has more than 700 employees at the DLR site in Stuttgart. Six institutes focus on research in the fields of aeronautics, space, energy, transport and security. This also include the staff of the Institute of Combustion Technology.

The main objective in the development of improved combustion technologies is not only to increase efficiency and reduce pollutant emissions, but also to use alternative fuels in technical combustion processes in a cost-effective manner. The provision of secured and validated chemical model fuel reaction mechanisms is one of the central tasks of kinetics with the aim of achieving an improved computer-aided design and optimisation of technical combustion processes with conventional and alternative fuels.

FLOX Burners for Gas Turbines

For gas turbines, the FLOX® combustion concept presents a promising alternative to the widely used swirl burner. In FLOX® burners, fuel, air and burned gases are intensely mixed in the combustion chamber before the onset of flame reactions. This leads to a quite homogenous temperature distribution and reduced peak temperatures, thus avoiding significant NO formation.

EnerTwin micro gas turbine

The EnerTwin micro gas turbine has an electrical output of 3kW and a thermal output of 14 kW. The micro gas turbine compresses ambient air to 3 bar (full load) using a radial compressor.

The main topics of research and development activities at the Institute of Combustion Technology (VT) are technical combustion processes focused on combustion in gas turbines. The fundamental goal is the optimisation of gas turbine combustion chambers with regard to efficiency, flexibility, reliability and emissions. In addition, new technologies should be developed and achieve marketability in cooperation with industrial partners.

A guiding theme of the Institute is the bridge spanned from combustion science to combustion technology. About 100 members of staff work in the specialist areas Chemical Kinetics, Computer Simulation, Gas Turbines, Combustion Diagnostics, Multiphase Flow and Alternative Fuels, Chemical Analytics, High-Pressure Experiments and Mass Spectrometry. The institute was founded in Cologne and moved to Stuttgart in 1965, where it was renamed into the Institute of Combustion Technology in 1998.
