Review of critical parameters in biomass combustion emissions control by means of hybrid filter

Abstract

Control of particulate matter emissions by means of hybrid filter has been included in the experimental plan of a research project in the field of Mediterranean agro-forestry waste biomass combustion at medium scale. Application of hybrid filters to biomass combustion has not been thoroughly experimented so far. An identification of the most important parameters in particulate matter emissions control by means of a hybrid filter was undertaken. The filter involves two of the most significant technologies in fly ash emission control, electrostatic precipitation and fabric filtration A discussion of these parameters and principles of operation of said technologies is presented, as well as the final selection of parameters to be included in the experimental matrix of the project in regards to emissions control. A novel approach is proposed for testing of filtration velocity influence in fabric filter module without impacting on operation of electrostatic precipitation module.
