Existing reaction mechanisms for the combustion of syngas consider only chlorine or only sulphur compounds, which limits their predictive ability. In this study, we defined a unified reaction mechanism that considers the syngas combustion in the simultaneous presence of chlorine and sulphur compounds and accurately predicts the effects of these compounds. We reduced the combined mechanism to obtain a mechanism suitable for use in 3D CFD simulation. Both mechanisms were validated based on data from literature. The mechanisms enable improved predictions of syngas combustion in the presence of chlorine and sulphur compounds.
