Development of a Highly Flexible 20–100% Hydrogen-Blending Combustor for Light-Commercial Boilers via Advanced Aerodynamic Design and H2 Mode-Switching Control
Short Introductive summary
Researchers from the Institute for Advanced Engineering (IAE) and Innoen Inc. have developed a versatile 150,000 kcal/hr combustor for light-commercial boilers capable of operating with a "super variable" hydrogen blending ratio of 20% to 100%. - Innovative Control & Design: To mitigate flashback risks and high NOx emissions, the system utilizes an automated mode-switching control algorithm that adjusts the excess air ratio based on hydrogen concentration. - Aerodynamic Engineering: The hardware features a multi-nozzle, circular flame port configuration that stabilizes combustion through Central and Peripheral Recirculation Zones (CRZ/PRZ). - Environmental Impact: The project targets ultra-low NOx emissions (35 ppm or less) and supports global carbon neutrality goals by allowing industries to transition from natural gas to zero-carbon fuel. - Global Readiness: An 80,000 kcal/h prototype is currently undergoing testing at Fraunhofer UMSICHT in Germany as part of the rigorous European H2-Ready certification process.
