<b>Abstract.</b> Predicting turbulent flow field in industrial incineration equipments requires that simplified chemical reaction mechanisms be developed in a case-by-case basis. In the present paper, reduced chemical kinetic mechanisms are developed, with the objective of capturing part of the time scales involved in a detailed mechanism for a mixture of hydrocarbon, sulfur and ammonia gases. This development is made using a perfectly stirred reactor and an adiabatic thermal explosion (Semenov explosion) model. All representative species involved in the process are considered and different operating conditions are investigated. The computational results highlight the shortcomings and the advantages of the two reduced schemes by comparing with the initial detailed mechanism.
