Experimental Study of the Performance of a Laboratory-Scale ESP with Biomass Combustion: Discharge Electrode Disposition, Dynamic Control Unit and Aging Effect

The increasing use of biomass combustion systems as household appliances for heat generation is causing concern about local air quality. Areas with high concentrations particulate matter (PM) emissions are linked to health risks. There a need removal device that collects the particles before they reach atmosphere. Electrostatic precipitators (ESPs) most suitable option. In this study, laboratory-scale prototype ESP was tested pellet boiler. Retention efficiencies above 90% were obtained three different discharge electrode dispositions. continuous operation achieved dynamic control system despite fluctuations in emissions, gas conditions, etc. accumulation on inner surfaces over time reduced effectiveness electric field, and thus retention efficiency. efficiency fell from 31% 34 h.
