Paper GT2021-59592 at ASME Turbo Expo 2021
MOeBIUS stands for a Momentum-Enhanced Blend of the Reactants With Recirculated Burnt Gases. It is a novel concept for high-efficiency and low-emission combustion, developed by CBOne with the support of the FFG.
The concept and the combustor design are presented at the ASME Turbo Expo 2021, Virtual Conference and Exhibition: June 7 – 11, 2021. Its principle is called recursive sequential combustor, a synonym for arranging the burners behind each other and in a circle, so that a considerable part of burnt gases emitted by one burner enters the next.

Patent AT523924B1: Recursive Sequential Combustion
- Details
- Published on Thursday, 20 January 2022 14:15
We at CBOne are very proud to announce the recent grant of this patent related to our MOeBIUS technology, which could become a game changer!
Recursive sequential combustion allows the circulation of a large quantity of burnt gases in the loop formed by an annular combustion chamber. The recirculated combustion gases maximise interaction with the fresh reactants and make the hot core more heat conservative. All burners are arranged in a ring, literally placed one behind the other. The inlet and exhaust gas paths are located in the walls. This unique concept leads to positive effects such as robust lean operation and excellent NOx and soot performance.

Blueprint of the pressurised combustor used in the emootion project.
This year, two articles are presented:
- The first one is the project emootion, about the combined optic-acoustic precision monitoring of a flame in continuous flow machines. We show how this miniature monitoring system, developed at first for gas turbines can be used for atmospheric burners and heavy-use applications.
- The second topic is the project rePorT, about advanced burner design with integrated instrumentation. Instead of starting from an existing design - or conventional design - we show how a novel swirler shape was designed using additive manufacturing, and how this shape presents a lower pressure than a conventional swirler. This approach can result in significant gains in terms of weight and congestion. Combined to additional features such as the instrumentation, it simply leads towards better burners.
