In order to obtain the rate equation of coke combustion which can be applied to the mathematical model of sintering process, combustion rates of coke in beds packed with mixtures of coke particles and alumina spheres were measured under various experimental conditions. A mathematical analysis was conducted on the data obtained by the experiments. AS a result, the following coke combustion rate in the bed R^*_c was obtained : R_c^*=n_c4πr_c^2 (1/10.3K_c+1/0.5K_f)^<-1>Co_2 where, K_c is rate constant of chemical reaction, which was proposed by Parker and his co-worker, and K_f is the diffusion coefficient of oxygen through the gas film as proposed by Shirai. This equation will be applicable to the mathematical model of sintering process as the combustion rate of single-type coke which does not have any adhered fine materials and is one of the existing conditions of coke particles in the raw mixture of sinter.
