Description
The combustion of Hydrogen in Gas Turbines plays a crucial role to achieve the goal of a carbon neutral future. However, the combustion of Hydrogen leads to higher flame temperatures and therefore NOx emissions, especially in Aerospace applications but also decentralized electric energy production like data centers where water injection, multi-step combustion and exhaust gas aftertreatment are not an option. [1]
The patented method of Recursive Sequential Combustion “MOebIUS” offers a possible solution for the NOx issue and at the same time increasing robustness a lean combustion process of by looping large amounts of burnt gases within an annular combustion chamber, however a lightweight realization of this technology was not feasible with conventional production processes. [2][3][4][5]
This work reveals a successfully tested novel design of a potentially monolithic MOebIUS burner made of Nickel super alloy IN718 by using the freedom in design offered by Laser Powder Bed Fusion.
