| Abstract: | A cylindrical porous media model for waste lump in mass burning incinerator was established.Its axial and radial effective conductivities were derived respectivelies,at different gas velocities,different gas temperatures and different waste sizes.The temperature distribution inside the waste lump and the curves of the relationship between the center temperature and the heating time were obtained by means of two dimensional unsteady heat transfer. |
