Performance analysis of a small-scale electrostatic precipitator with biomass combustion

Biomass is commonly used for heat production in small-scale and domestic facilities. Particulate matter (PM) emissions from the combustion of solid biomass are a concern because hazards to human health. Electrostatic precipitators (ESPs) have been supported as most promising mitigation technology, although there lack consolidation provide promulgate solution. The currently published studies on do not offer deep performance analysis an electrostatic precipitator; instead, different designs presented validated through efficiency measurements. In this work, easily attachable ESP design tested more deeply analyse its with pellet boiler, measuring retention function PM sizes generated by under influence supplied voltage geometry considering discharge electrode diameters. Increasing give higher separation efficiencies until 90% reached, further improvements remarkable. This value influenced limitations particle analyser. A thinner achieves both better stable operation at lower than thicker electrode. Regarding size, capacity particles between approximately 0.17 μm 0.7 due reduced ability charging mechanisms. formation agglomerates during re-entrainment also observed.
