Abstract
In this study, a CFD model of entrained-flow gasification of petroleum residue proposed to simulate the effects of some critical parameters such as equivalence ratio and system pressure on carbon conversion efficiency, tar yield, hydrogen concentration, and higher heating value of the syngas. It is a 2D model and steady state, which can be used as a general model to evaluate the performance parameters of other fuels (coal, biomass, and municipal solid wastes) during gasification process. Results showed the equivalence ratio has a negative effect on the higher heating value of the syngas and a positive impact on the gasification efficiency. It also found that the carbon conversion efficiency strongly depends on the equivalence ratio and gasification temperature. The model validated against experimental observations and found to be in good agreement.
