Abstract：Numerical simulation is conducted on convection heat transfer in cylindrical tube type furnace radiation chamber. Adopted is a jet flow model to divide the radiation chamber into such three areas as the same quality area，jet flow area and backflow area according to different conditions of smoke movement，adopted are different boundary conditions for limiting the areas，mathematically described are the three areas respectively and realized is the calculation process by using VB language programming. Taking a normal pressure furnace for example，simulation calculation is conducted on outer wall temperature of furnace tubes in the radiation chamber and adopted is the Monte?鄄Carlo method for radiation heat transfer calculation. Outer wall temperature distribution of furnace tubes calculated through comprehensively considering radiation heat transfer and convection heat transfer is compared with that calculated through only considering radiation heat transfer，the former is more identical with theoretically inferential value.
