Abstract: The effects of adding different proportions of convert sludge on the shock temperature of pellet were investigated in this paper.The result shows there exist adverse effects.When the convert sludge is added,the porosity goes down.Under the condition of usual external temperature the effective diffusion coefficient of the water vapor becomes diminished and the water vapor pressure of internal pellet goes up,which leads to the shock temperature reduction.Therefore,when the oxidized pellet is prepared by addin...
