Experimental investigation on combustion behavior of pulverized silicon – part 1: Influence of particle size

Year: 2026

Type: article

Abstract: • Stable silicon powder ignition at 1300 °C in a drop tube reactor for minutes. • Finer particles oxidise faster, raising local temperature and NOx levels. • Bowl feeder ensures homogeneous, clump-free fuel dosing. • Measurements of temperature and electric heater indicate an exothermic reaction. • SiO₂ layer and agglomeration affect the progress of oxidation.
