Research
The Chair of Energy and Environmental Process Engineering, headed by Prof. Dr.-Ing. W. Krumm, specializes in mathematic modeling and simulation of complex process engineering systems and experimental studies of pyrolysis, gasification and incineration of biomass, coal and residues. In cooperation with medium-sized companies, we design and develop to market technical equipment for the field of environmental and process technology, closely considering factors such as cost, energy consumption, environmental impact and sustainable development.
