Successful Maiden Fire for the First Full AM-Burner Designed by CBOne!

Ok - the title for this article was temporarily changed to "* * Ô la Belle Bleue  !!! " because of some footballistic interference during the summer 2018. Shortly said: Bravo les Bleus, Merci pour cette deuxième étoile! That was it, back to combustion now! 

The first full 3D printed burner designed by CBOne was tested with success. 

This validates our capacity to design a complete burner fit for operation under gas turbine conditions (natural gas-fired, premixed lean combustion, two-stage with a low swirl pilot embedded in a high swirl main), with additional features versus conventional such as a monolithic form, low finishing requirements, advanced thermal management, integrated ignition and prepared instrumentation ports for an advanced monitoring.

Additive Manufacturing: The New Forge (Turbo Expo 2018)

The freedom of design using Additive Manufacturing (AM) opens the door towards new shapes and new designs. In combustion engineering, this is the opportunity to make better burners.

CBOne was present at the ASME Turbo Expo in Oslo, Norway, from the 11th to the 15th of June 2018. In collaboration with our colleagues from Joanneum Research GmbH and FH JOanneum in Graz, Austria, we made a study about shape factors for a novel type of swirler.

Joint Forces on Additive Manufacturing of Premium Parts Designed for Extreme Thermal Strains

The Research Center JOANNEUM RESEARCH, the University of Applied Sciences FH JOANNEUM and the Engineering Office specialised in advanced combustion management COMBUSTION BAY ONE join their forces and design the better burner together. CBOne is in charge of the design, FHJ is in charge of the modelling, and JR is in charge of the commissioning using additive manufacturing of metals (PBF / Powder Bed Fusion). To seal this commitment about better burners produced with additive manufacturing (AM), the three parties have signed in October 2017 a common letter of intent.

CBOne and JR take part in a pilot study on Additive Manufacturing using Inconel 718 (FFG contract 862837). A common publication with the participation of FHJ is planned 2018.  The figure shown is the first result of this study - shortly said it works and it works well.

Energy Innovation 2018: New Frontiers

CBOne is present at the Symposium EnInnov 2018 on Energy Innovation at TU Graz, from the 14th to the 16th of February.

Blueprint of the pressurised combustor used in emootionBlueprint 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.
