Patent EP4729299A1: CBOne invents ... the knitted combustor!

We are proud to announce that our sixth invention has been patented under the numbers AT528115B1 and EP4729299A1. It involves connecting flowing shapes with the thermodynamics of two fluids: one flowing within the shape and one flowing outside it, as in a heat exchanger, for example. This includes the novel Mathematics To Shape approach that you can also find on our matosha website.

Patent EP4471330 A1: CBOne invents... the rapid premixer!

2024 was an exceptional year for industry services and R&D at CBOne. We are very happy to conclude the year with the publication of a European Patent, coming from the project we conducted from 2021 to 2023 called Bluetifuel. This is about the safe and low-NOx combustion of hydrogen. In this fifth patent of our IP portfolio, P&P Industries GmbH owns the patent and will see that the technology is deployed, e.g. in the fields of process engineering and energy. CBOne is the inventor. 

The Bluetifuel burner burning hydrogen at 1MW, with less than 15ppm NOx

Patent AT519720B1: Combined Optic-Acoustic Compact Probe and method for monitoring combustion processes and/or an ignition process

An advanced sensing system analyses the sound and light emitted by the flame. This device is called RCP probe for "Rayleigh Criterion Probe", or simply the emotion probe in connection to the em(o)otion technologies developed jointly by CBOne and FH Joanneum. This contribution has the patent reference A 50160/2017.

Technical and scientific publications:

The collaborative research project “em(o)otion” was supported financially since 2015 by the FFG (Austrian Research Promotion Agency) and by the BMVIT (Austrian Federal Ministry for Transport, Innovation and Technology). The project about “Engine health monitoring and refined combustion control based on optical diagnostic techniques embedded in the combustor” was supported by the Austrian grant for applied research in aviation called the “Take-Off” program, contracts 850470 (emotion, 2015–2017) and 861004 (emootion, 2017–2020).

Patent US12013122B2: Recursive Sequential Combustion

We at CBOne are very proud to be inventor and owner of the international patents US12013122B2, EP4222361B1, WO2022067359A1 and AT523924B1 related to our MOeBIUS technology, which could become a game changer for gas turbine combustion!

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.

Patent AT522614B1: Method & set-up for a well repeatable injection of fuel and oxidant

The technology protected by this patent was developed within the explorative project ”rePorT” (Instrumented fuel injection ports for advanced monitoring of the injection in the combustor of an aeroengine, contract FFG / Take Off Call 2014 / 850454).  Additional intellectual property tasks were supported by the FFG / Patent.Scheck / Project 870672: rePeat IP (Repeatable injection conditions, IP chapter). 

The rePeaT project has three key principles:

  • The first is a technical arrangement for injecting into a turbine burner injector to avoid overheating of the fuel and the resulting clogging of the injection holes and distribute it in a well-repeated manner. It involves the feedback of a given quantity of fuel.
  • The second is a method of fuel flowmetry related to the first idea. It is based on the simultaneous measurement of the pressure and temperature of the fuel in the injector in the return circuit.
  • The third idea is a technical arrangement involving 3D printing, allowing the technical implementation of the two first ideas.
