摘要
Seven typical components in municipal solid wastes (MSWs)--paper,food,textile,wood,straw,plastic and rubber were chosen as the thermogravimetric analysis samples in this paper to study the pyrolysis characteristics. By the thermogravimetry and differential scanning calorimetry (TG-DSC) analysis,pyrolysis characteristics of MSWs’ components and pyrolysis endothermal enthalpy were obtained.The kinetic parameters of pyrolysis were determined with the Doyle method and a multi-stage first order pyrolysis model was proposed.The simulated results by this model showed good agreement with the TG experimental data.The pyrolysis characteristics provide significant parameters to a new concept of circulating fluidized bed incinerator,which can simultaneously restrain the high-temperature HCl corrosion and emission of dioxins.
