Model analysis of combustion of single RDF pellets

摘要

An unsteady model of the combusion of a single RDF pellet,which involves heat transfer and oxygen diffusion in the RDF pellet,was developed to interpret quantitativley the devolatilization and the char combustion processes of RDF.The simulation results for weight loss and temperature profile of the RDF samples made from municipal solid wastes,wood chips and polypropylene when they were heated at 10K/min or put into the furnace at 1,073 K were verified toagree with the experimental data.RDF pellet during the devolatilization process and the char combust in process using this model,the influence of heating rate on the combustion characteristics was clarified.
