The effects of coal dust concentrations and particle sizes on the minimum auto‐ignition temperature of a coal dust cloud

Fire and Materials, 2017
SummaryFlash fires and explosions in areas containing an enriched combustible dust atmosphere are a major safety concern in industrial processing. An experimental study was conducted to analyse the effects of atmospheric coal dust particle sizes and concentrations on the minimum auto‐ignition temperature (MAIT) of a dust cloud.
