The discrete ordinate approximation method of three dimensional radiative transfer equation in absorbing-scattering medium is expounded. The causes about the formation of false scattering and ray effect and its influence on the accuracy of solutions are also analyzed. The process of radiative heat transfer in a three dimension rectangular furnace is simulated using discrete ordinates method, which has good accuracy and is recently found as the best to simulate the process of radiative heat transfer in furnace in comparison with zone and discrete transfer method.
