Influence of Particle Size, Moisture, and Cloud Density on Wood Dust Ignition
Chemie Ingenieur Technik, EarlyView.The ignition and combustion of particle clouds are strongly affected by particle interactions. This study uses spectroscopy to examine effects of particle size, water content, and cloud density. Results show ignition delay rises with larger size and density, whereas combustion duration depends mainly on water and density due to moisture‐driven ...
