Development and automated design exploration of a novel Dry Low NOx Hydrogen combustion technology for gas turbine applications
Combined with the use of renewable energy sources for its production, Hydrogen represents a possible alternative gas turbine fuel for future low emission power generation. Due its different physical properties compared to other fuels such as natural gas, well established gas turbine combustion systems cannot be directly applied for Dry Low NOx (DLN) Hydrogen combustion. This makes the development of new combustion technologies an essential and challenging task for the future of hydrogen fueled gas turbines. The DLN Micromix Combustion technology has been successfully developed to address this challenge. Thereby, a systematic design exploration has been performed using HEEDS and STAR-CCM+®, allowing the identification of complex relationships between design parameters and their impact on the burner’s performance. Thorough analyses of CFD results helped to understand complex physical interactions between aerodynamics, combustion and emission formation of different burner configurations within the explored design space. This numerical approach reduces development time and cost significantly, since experimental testing was diminished to validation campaigns, which have confirmed lowest NOx emissions and highest combustion stability of the developed pure Hydrogen Micromix burner, providing a mature key technology for the use of Hydrogen within the future low emission power generation.
