Patent AT519720A1: 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 also has the pending joint 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 AT522614A1: Method 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 tasks connecting with the intellectual property 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.

Better, safer, cleaner combustion

How can one drastically reduce fuel consumption? If the margin in terms of gains in efficiency at the main operation point is low (less than 5% using conventional combustion on most of the thermal facilities), the margin in terms of fuel savings at off-design operation is much greater. 

Combustion technologies can be improved. Furthermore, the operating costs of thermal facilities can be reduced while improving safety. We address these affirmations with three flagship projects at CBOne: MethaNull, rePorT, and emootion.

 

At Combustion Bay One, we own these technologies, we fine-tune these and we regularly publish our results.

Patent AT516424B1: The Pilot Flame as a Tuneable Thermoacoustic Driver for Combustion Control

The patent about the MethaNull technology is granted. The idea is the precision drive of thermoacoustics for a positive impact on the combustion quality using a pilot burner, and the related method makes use of a siren as an exciter.

At the occasion of the recent publication on our patent AT516424B1 (link EPO/Espacenet, link Austrian Patent Office, link Google patents), here is a brief overview of the invention.
