中文摘要	An implicit iterative method was developed to solve particle energy equations with the discrete ordinate method used to obtain the radiative intensity distributions in a utility furnace. This implicit iterative method is shown to be more stable and to converge faster than the conventional method based on ordinary difference equations. Single particle combustion simulations show that the particle radiation affects the particle heating, annealing and burn-out processes, and provides about 50% of the total heat exchange from the particle and extends the particle burn-out time. The particle radiation increases the flame region temperature while reducing the flue gas temperature near water walls. Comparisons also show that the particle radiation effects improve agreement between the simulation results and experimental data.
