No.52 微粉炭チャー燃焼のモデル化とシミュレーション(ガス化・燃焼・液化(1))

抄録

In this report, a char combustion model was examined, which has three important features: and accurate estimation of diffusivity in a multicomponent system in a fluid film, an expression of particle shrinkage consistent with the Random Pore Model, and numerical integration of physical quantities inside a particle. our char combustion model was validated using the char oxidation data obtained using a drop tube furnace, and it was demonstrated that the model can precisely capture characteristics in the wide range of temperatures and stages of carbon conversion.
