The temperature field, the velocity field of fluid and the concentration distributions of CO, CO and water vapor are obtained during the combustion, and 2 the measured values are compared with the numerical simulation results. The results show that the average measured value of the maximum temperature of flame is 870℃, and the numerical simulation value is 1007 ℃. The relative error above is 15.75%. The average measured value of concentration of 25 CO in gas is 0.053%, and the numerical simulation value is 0.064%.The relative error above is 20.75%. The average measured value of concentration of CO in gas is 4.27%, and the numerical simulation 2 value is 4.73%.The relative error above is 10.77%. The average measured value of thermal efficiency is 44.10%, and the numerical simulation value is 46.36%.The relative error above is 5.12%.
