A study of the pyrolysis behaviors of pelletized recovered municipal solid waste fuels

► Heat transfer and devolatilization properties of pelletized municipal recovered solid waste fuels were investigated. ► Significant swelling was observed during pyrolysis of pelletized municipal recovered solid waste fuels. ► SEM images of char produced from the pyrolysis of recovered solid waste under different temperature were analyzed. ► A detailed discussion was given for the mechanism of the swelling phenomena during the pyrolysis of recovered solid waste.
