INFLUENCE OF OPERATING CONDITIONS ON BAG FILTER PERFORMANCES FOR INCINERATION FUMES TREATMENT

Abstract : Filtration performances of a bag filter implemented for the flue gas treatment of waste incineration plant were studied at laboratory scale in order to evaluate the influence of filtration cycles (clogging/unclogging). The filtration performances were evaluated during clogging with a submicronic aerosol with nano-size fraction, at a filtration velocity of 1.9 cm.s-1. Investigations of the influence of filter washing and filtration velocity on the filtration performances were performed with the same filtering media in flat configuration. Experimental results showed an influence of filtration velocity on fractional filtration efficiency in particular for particle diameter close to the Most Penetrating Particle Size of the filter. Moreover, results indicated that new filters were significantly less efficient than washed filters at the beginning of the clogging. Finally the influence of clogging/unclogging cycles on bag filter performances was demonstrated both for pressure drop and filtration efficiency evolutions during clogging.
