The Institute of Energy Systems and Technology at Technical University of Darmstadt has long experience in the field of power plant and energy process technology, particularly in solid fuel conversion and CO2 capture processes using fluidized bed systems. Its key expertise includes experimental investigations in lab- and pilot-scale test facilities, CFD simulation of dense particulate flows, and process simulation of energy systems. The institute has operated a 1 MWth chemical looping pilot plant with various fuels, such as coal, biomass, and wastes. Furthermore, TUDA has developed dedicated process and CFD models for chemical looping combustion.
Role in Bio-FlexCLC:
Technical University of Darmstadt performs tests at its 1 MWth pilot plant to demonstrate the innovative chemical looping concepts developed in this project (i.e. operation of a flexible CFB-CLC unit, fuel flexibility, and packings in the fuel reactor) in an industrially relevant environment. SOx and NOx concentrations in the off-gases are measured to define appropriate measures for emission control. Cooled online corrosion probes are inserted into the off-gas ducts to evaluate the effect of the operating conditions on the corrosion rate. Furthermore, unsteady process simulations are performed to study the dynamic behavior of a chemical looping CHP plant during changes between the steady-state operating points.
