The effects of the installation of division walls in large-scale furnaces for thermal electric power plants are demonstrated by numerical analysis of combined radiative and convective heat transfer in the furnaces using a radiative ray tracing method. The changes in the profiles of gas temperature and wall-heat flux and in the furnace efficiency are calculated for different numbers and sizes of the division walls. From the analysis, the following results are obtained. 1. The installation of division walls reduces the average gas temperature and maximum wall-heat flux and increases the furnace efficiency. 2. Among the configurations of division walls with the same surface area, the ones with walls which extend to the center of the furnace have the higher thermal efficiency.
