Abstract
In this paper, we investigate the exergy analysis of the combustion chamber supplied by different fuel compositions based mainly on methane and/or hydrogen in order to select the optimum fuel composition case for the economic combustion. For this, the analysis process considers the variation for both parameters: mass flow rate and equivalence ratio. This is to characterize all fuel cases. The calculations are based on the prediction of three variables: the exergy destruction and the exergy universal efficiency, the contribution of exergy destruction sources and the effect of fuel composition on these sources. Therefore, all computations of this investigation are carried out by the Cycle-Tempo Release to determine the appropriate fuel composition. In the overall, the obtained results show that the hydrogen enrichment methane flame has an impact on the combustion efficiency.
