Abstract—Thermodynamic irreversibility significantly limits fuel energy conversion into useful work. Hence, the evaluation of thermodynamic irreversibility is an important aspect in the development of combustion techniques for better fuel utilization. This evaluation is performed for the HTAC (high-temperature air combustion) process through entropy generation analysis. The primary irreversible processes of HTAC are determined and the influence of key operating parameters such as the combustion air temperature, and oxygen-dilution are studied.

Index Terms—Combustion, entropy generation, HTAC mode, thermodynamics.
