To discuss the possibility of furnace harmonization, heat transfer in fire resistance furnaces were analyzed numerically. The analytical model included radiative and convective heat transfer between surfaces and gas volume. The heat exchange between thermocouple and its surroundings was taken into account in order to simulate the furnace control process. The model was verified by comparison with experimental data. By using the model, calculations were carried out for various furnace depth, fuel, wall lining materials and the geometry of thermocouples for furnace control. From the calculated results, it was concluded that the wall lining material is the main factor that controls the heat impact on specimen. The geometry of thermocouple is a secondary factor.
