| Abstract: | In order to get a thorough understanding about the interior reactions in Texaco gasifier and provide information for further development of residual oil gasification process, a comprehensive mathematical model for simulation of residual oil combustion has been developed in this paper. RNG k-e model was employed to describe the turbulence of continuous gas phase and simplified-PDF model for chemical reactions, discrete ordinates model for radiation were also used. The contours of inner temperature, velocity and the distribution curves of CO and H2 were obtained with the models presented. These simulation results were in good agreement with the plant operation data. |
