Pyrometric and Spectroscopic Measurements of Temperatures of Metallic Dust Combustion Ignited by Characterized Spark Discharge in a Hartmann Tube

A spark discharge with variable duration has been used to ignite aluminum, aluminum–silicon alloy, and magnesium powders inside a Hartmann tube to evaluate explosion hazard. Pyrometric and spectroscopic methods have been performed to measure burning particles’ temperature and gases’ temperature, respectively. The spark discharge is also characterized to achieve a better understanding of the interaction between the metallic dust cloud and the spark during the ignition time. Since realistic experimental data are strongly in interest for computational fluid dynamics, in this paper, one provides ignition spark temperature and combustion experimental data such as ignition delay, particle temperature, gas temperature, and electron density.
