Micro-Explosion mechanism of iron hybrid Methane-Air premixed flames

Minimum Fluidization Velocity and Reduction Behavior of Combusted Iron Powder in a Fluidized Bed

“…The combusted particles are mainly spherical, but some of them are tulip shaped hollow shells, resulting from micro-explosions (see center image in Fig. 1 for an example), as already observed in previous studies [34][35][36][37][38]. The particles show different surface roughnesses, most likely resulting from different combustion profiles.…”
