Abstract
To provide a first insight into combustion characteristics of ammonia-based fuel in gas turbine engines for power generation, a generic swirl burner is tested with ammonia/hydrogen mixtures in this study. Based on the Computational Fluid Dynamics (CFD) simulation results, Chemical Reaction Network (CRN) model is developed to study the NOx emission characteristics of different ammonia/hydrogen mixtures in a gas turbine swirl burner. The NOx emission results predicted by the CRN model using Konnov’s mechanism have shown satisfactory agreement with the experimental data. The parameter study are then performed to estimate the effect of pressure, inlet temperature and equivalence ratio. Areas are identified which more attention for model development and emission need control in future studies.
