Applicability of a coal combustion model was validated by using experimental data of utility boilers. The coal combustion model had gasification and NO_X reaction submodels and it was developed by using a small drop-tube-furnace (coal feed rate 0.6kg/h). A turbulence combustion simulation program was developed by introducing the coal combustion model. The simulation program was validated by comparing with twenty three experimental results that contained different plant, load and coal data. The temperature difference between simulated and experimental results was less than 30 degrees C at the exit of the furnace. The characteristic of coal burnout that was decreased with increasing load was predicted. The NO_X concentration difference between simulated and experimental results was less than 15 percent. The coal combustion model was applicable to the utility boilers as same as the drop-tube-furnace.
