Abstract
A heat transfer model of the coke oven chamber is proposed considering the radiation within the macro fissures in the coke and the convection of the product gas.Contributions of the radiation and convection to the temperature distribution in the coke oven chamber are numerically observed under the various conditions concerning the fissure width and the direction of the gas flow. As a result, it is found that both of them cannot be neglected in the heat transfer analysis in the coke oven chamber since they have the significant effects on the temperature distribution.<BR>By using a newly proposed thermal property estimation method, the thermal conductivity and the heat capacity of coal are estimated from temperature distribution computed by the model mentioned above.Thermal properties of coal which are estimated from the temperature history in the coke oven chamber are suggested to be much different from the true values and to have no generality.
