Abstract
In this study, numerical modeling of ammonia-hydrogen fuels (10%–50%) in a turbulent eddy gas turbine combustion chamber with different cooling angles (15, 30, 45) have been performed by using a computational fluid dynamics code. It has been observed that the maximum temperature levels in the combustion chamber decrease with the addition of ammonia and the flame moved towards the exhaust of the combustion chamber because of the lower burning rate of ammonia in the regions where the flame occurs. Although the addition of ammonia in the combustor increases the NOx levels in the flame core rapidly. The 45° provides a more homogeneous temperature distribution compared to other conditions with 15–30° inclination angles at the outlet. As a result, it can be concluded that ammonia-hydrogen blended fuels have a substantial possibility as an option and sustainable fuel in terms of combustion performance.
