Computational Fluid Dynamics (CFD) Assessment of the Internal Flue Gases Recirculation (IFGR) Applied to Gas Microturbine in the Context of More Hydrogen-Enriched Fuel Use

Renewable energy is a promising substitute for fossil fuels when corelated with P2G technology. To optimise efficiency, there need to increase hydrogen fraction in the fuel stream. Simultaneously gas microturbines are widely applied many industry sectors. These devices often equipped diffusion combustors. This situation was investigated this paper. The and may be integrated together future leading application of hydrogen-enriched fuel. Hydrogen-enriched causes combustion temperature velocity. In nonadapted combustor, these phenomena could result an NOx emissions risk material overheating failure. order adapt combustors fuel, concept autonomous internal flue gases recirculation (IFGR) system issue. paper, IFGR microturbine studied terms application. obtained exhaust ratios were too low affect process as it expected. observed modifications combustor hardly linked air flow modification liner, due implementation. After CFD studies, proposed does not seem provide expected effects.
