Combustion of Lithium Particles: Optical Measurement Methodology and Initial Results
Combustion examinations on the single-grain level were carried out in order to get further fundamental insight into the ignition and combustion of lithium particles. Combustion of solid lithium particles in a defined size fraction was analyzed in a laminar-flow reactor. The exhaust gases of a methane-air flame provided the reactants O-2, CO2, N-2, and H2O for the lithium conversion. Two different atmospheres at various temperatures were investigated. A high-speed camera system measured size and radiation intensity of burning particles. The results indicate that two different combustion phenomena occurred in lithium combustion. The first was identified as a homogeneously enveloping flame around the lithium particle and the second as a reaction zone next to the particle surface.
