The present study discuss about numerical simulation to analyze design parameters of a coal gasifier. Three different burners were analysed by computational fluid dynamics and its results were compared with experimental results. A commercial code (FLUENT V 6.3) was applied to simulate the energy transport including coal surface and gaseous reactions, radiation and turbulent flow. The numerical results showed how the burner shape affects the reaction and thermal environment of the reactor, and showed good agreement with the experimental results at one burner shape. However, it was not successful to predict the experimental results at the other burners due to limitation of numerical model which cannot simulate the melting of the coal particle at high temperature. When the temperature near the coal particle is too high, the particle could be melted and the reaction surface area decrease so that the reaction performance is low, which is far from the numerical result. Hence, the numerical results should be carefully discussed and evaluated when the gas temperature near the coal particles is extremely high(>3000℃).
