Three-Dimensional Analysis of a Steam-Injected Gas Turbine Combustor Fuelled by an Ammonia-Hydrogen Blend
Abstract
Abstract This work presents a 3D numerical study of a steam-injected combustor for a gas turbine operating on an ammonia-hydrogen fuel blend, aimed at enabling carbon-free hybrid energy systems. The research focuses on the performance and emission characteristics of a 32 MW engine’s combustor. Using Computational Fluid Dynamics (CFD) with a detailed chemical kinetics mechanism (203 reactions, 31 species), the model solves the governing equations for turbulent reacting flow. The simulations provide new insights into ammonia-hydrogen flame propagation within intensely swirled flows under staged air and steam admission. Key energy and environmental parameters for the combustor are obtained. The results support the design of advanced combustors for decarbonised gas turbine systems.
