Aluminum particles are widely used as an additive to increase energetic performances. Recently, Aluminum has also received a growing interest as a source of hydrogen for fuel cell applications, or in novel power generation concepts as it provides a carbon-free energy that meets current policies for reducing emissions of greenhouse gases. Our recent studies focused on the description of the combustion process varying ambient conditions (pressure and oxidizer). Only the second stage of the combustion process, after the establishment of a steady state, was scrutinized. The proposed work sheds light more specifically to the initial stages where the particle is warmed up from the initial state to a thermal runaway condition. Indeed, the question arises at what temperature do these condensed fuels burst into flames, knowing that the presence of a passive coat greatly influences the process. For this study, a dedicated set-up has been improved. It consists of an electrodynamic levitator in which a single particle, trapped by electrostatic forces, burns in a controlled atmosphere. A two-color ratio pyrometer has been specifically assembled with photomultipliers (PM) to obtain the time evolution of mean surface temperature. The PM signals are synchronised witha particle visualization device that is composed of a high-speed camera combined with a long-distance microscope. Subsequently, the temperature measurement of high temporal resolution can then be associated for the first time at a rate of 250 000 fps with the fast-apparent phenomenology of the pre-ignition processes. In addition, the spatial resolution of the visualization (1.92 μm/pix) allows the interpretation of the PM signals to be commented.
