Conventional particle emission measurement technology only takes into account the total emission and does not offer spatial resolution. Extensive troubleshooting is required in order to identify potential emission hotspots (e.g., small leaks) that contribute strongly to dust emissions. A network of inexpensive low-cost PM-sensors was used in a small-scale bag- house filter for spatial online particle emission monitoring. Different types of emission hotspots were investigated. Spatial PM monitoring enabled the reliable identification of the position of the hotspot as well as estimation of leak size.
