A numerical calculation method has been developed for the three-dimensional heat transfer analysis of industrial furnaces. This method can account for the distribution of radiative properties of flame, combustion gas and solid walls and also for the existence of heat sinks located at arbitrary places in a furnace. The energy-balance equations are formulated by taking account of radiation, convection, flow pattern, heat release and heat conduction in the refractory of walls. The calculation of fluid flow including heat release due to combustion is carried out using the k-ε two-equation model for turbulence and the eddy-dissipation model for combustion heat release. Two sets of calculations are separately conducted in turn. Firstly, flow pattern and heat release distributions are calculated under the isothermal condition by the finite volume method. These calculated results are used as input data for heat transfer calculation by the Monte Carlo method together with the zone method. Then the calculated temperature distribution is given to the second calculation routine. The calculation results from the third routine are confirmed to be acceptable for a practical error limit. The calculation procedures are applied to the heat transfer analysis of a heating furnace for a steel ingot and show its advantage in the practical usage for furnace design.
