Institut für Kraftwerkstechnik Dampf- und Gasturbinen
Research
The Institute for Power Plant Technology, Steam and Gas Turbines (IKDG) deals with the analysis and assessment of energy conversion systems, with the investigation and optimization of steam and gas turbines and valves for power plant applications and their integration into the power plant process.
The IKDG has several large test rigs, in which combustion processes in gas turbine combustion chambers or flow phenomena in steam and gas turbines, such as secondary flows in the blade channel and leakage flows in the shroud cavity and their interaction can be investigated. The aim of this research is optimization of the turbine aerodynamics and characterization of loss mechanisms. The increasing of power plants efficiencies is associated with the increase of the process parameters of turbines which requires the application of porous materials and improved cooling technologies. These topics are focus of research at the Institute for a long time.
The investigations of combustion processes aim at reducing of pollutant emissions and combustion instabilities. The latter induce combustion chamber humming in premix burners which is a threat to the safe operation of the gas turbine plant. These burners are in comparison to diffusion burners characterized by significantly lower NOx emissions.
Furthermore the Institute is concerned with power plant simulations. The interaction of the individual machines in a complex energy conversion system is analyzed in order to derive strategies for the optimization of the overall system and the components. Besides decentralized and hybrid technologies can be evaluated.
