Investigations of particle formation processes are an important field of research due to the multitude of applications in industrial facilities. The present article is focused on the investigation of Fe 2 O 3 ‐particle formation. The particles form during the thermal decomposition of an iron chloride solution in so‐called spray roasting reactors. For detailed analysis of the iron oxide formation a laboratory reactor was developed which simulates the boundary conditions of industrial spray roasting reactors. Temperature, gas composition, and droplet size are comparable to industrial application. To examine the influence of droplet size on the particle formation process, a droplet generator was installed which provides monodisperse size distributions. Furthermore, industrial constraints and first results are discussed.
