Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 49 N° 16 (Août 2010) . - pp 7597–7604 Titre : Modeling on - grate MSW incineration with experimental validation in a batch incinerator Type de document : texte imprimé Auteurs : Abhishek Asthana, Auteur ; Yannick Ménard, Auteur ; Philippe Sessiecq, Auteur Année de publication : 2010 Article en page(s) : pp 7597–7604 Note générale : Industrail chemistry Langues : Anglais (eng) Mots-clés : Solid waste incineration Résumé : This Article presents a 2-D steady-state model developed for simulating on-grate municipal solid waste incineration, termed GARBED-ss. Gas−solid reactions, gas flow through the porous waste particle bed, conductive, convective, and radiative heat transfer, drying and pyrolysis of the feed, the emission of volatile species, combustion of the pyrolysis gases, the formation and oxidation of char and its gasification by water vapor and carbon dioxide, and the consequent reduction of the bed volume are described in the bed model. The kinetics of the pyrolysis of cellulosic and noncellulosic materials were experimentally derived from experimental measurements. The simulation results provide a deep insight into the various phenomena involved in incineration, for example, the complete consumption of oxygen in a large zone of the bed and a consequent char-gasification zone. The model was successfully validated against experimental measurements in a laboratory batch reactor, using an adapted sister version in a transient regime.
