Resumo

Based on our previous work, in the present paper the parameters of geometry structure of ash layer are determined by using renormalization group theory, then a heat percolation model of thermal conductivity of granular materials is developed by the analogy of heat conduction in the ash layer to random resistor network. The model predication agrees reasonably with the experimental results.
