The project Clean Circles is dedicated to solving global energy problems by using iron as CO2-free, renewable and efficient chemical energy carrier. First, electricity from renewables is used to reduce iron oxide (energy storage). Then, the iron is oxidized to release thermal energy for electricity generation at a different place and time (energy release). In the collaborative research project, scientists and students from different Universities work closely on numerous experiments and simulations.
In this student work, a new metal particle ignition reactor (MPIR) with well-defined boundary conditions should be designed and tested for single iron particle experiments. MPIR will include three modules: electrostatic-based single particle generator, an optically accessible ignition channel, and an external heating system by an annular gas flame. The concept of MPIR originates from the so-called micro-flow reactor (see Fig. 1), which has been successfully applied for gaseous and liquid fuel ignition studies. The advantage of this setup is to study the ignition/reaction kinetic by converting the trainsient process to a space-dependent process. Within this work, this concept should be realized for metal fuel ignition measurements.
The topic is suitable for ADP, Bachelor and Master theses, and the work tasks are adapted accordingly.
