Title: Cyclone optimization including particle clustering
Issue Date: 2015
Abstract: In this work, a new family of geometries of reverse-flow cyclones was obtained through numerical optimization,using a stochastic random search global optimizer coupled with the PACyc model. The objective was to optimizethe geometry of a reverse-flow cyclone taking into account inter-particle agglomeration (clustering), since thisphenomenon usually occurs to some degree in industrial cyclone operation, increasing the collection of fineparticles.Experimental results for three kinds of particles and particle size distributions are shown using a pilot-scaleunit. An industrial implementation of the new optimized cyclone is described and the results concerning theperformance of the system are shown and compared with predictions from the PACyc model.The results show a highly improved global efficiency when compared to that of a cyclone geometry obtained by asimilar optimization methodology while neglecting the agglomeration/clustering effect. This opens the possibility of using reverse-flow cyclones to capture very fine particles, complying with strict emission limits, such asthose from biomass boiler exhausts.
