Lump coke size is determined mainly by the growth of macro-crack from the wall side to center in the coke oven chamber, where the carbonization period and the coke quality are determined by the heat and mass transfer. Although the radia-tive heat transfer of porous media within the micro-crack can be included in an effective thermal conductivity, the effect of radiative heat transfer within the macro-crack on temperature and stress distribution in coal/coke layer have to be investigated analytical-ly using the finite element method.<BR>In this study, a rapid heating experiment of the brick with a macro-crack is carried out in the laboratory-scale coke oven to measure the temperature distribution in the brick. The heat transfer model including the radiative heat transfer within the macro-crack is estimated by comparing the calculated result with the experimental one in order to confirm the accuracy of temperature field in our ordinary thermal stress analysis model. As a result, the calculated history of temperature distribution in the sam-ple brick is in good agreement with experiments especially near the macro-crack surface.
