The air we breathe

A breathtaking picture in the Parisian outskirts during the pollution peak with particulate matter in Dec. 2016

Normally, at this time we publish our Season’s Greetings. However, this December’s headlines are about remarkable pollution peaks observed during week 49 (6-9.12.2016) in Mailand, Brussels, London and Paris. This time, the concentration in particulate matter was alarming. The exceptionally nice weather and its absence of wind just made things worse.

The alert for most large cities in Europe is given when a concentration in particle matter with size smaller than 10 microns (PM10) above 50µg/m3 is achieved. A sub-category of it is the group of particles smaller than 2.5 µg/m3. These are known to deposit in our breathing cavities and organs, and possibly interact with our blood. The WHO recommends a maximum concentration of PM2,5 of 10µg/m3. 

Quoting the European Environment Agency (EEA), "air pollution remains the single largest environmental health hazard in Europe, resulting in a lower quality of life due to illnesses and an estimated 467 000 premature deaths per year".

Roughly one third of these particles come from industrial combustion processes. And this is a figure one can reduce, namely with better combustion. This is what we do at Combustion Bay One.

Support CBOne by helping us to promote and deploy our MethaNull technology. We can bend these numbers. We can breathe a cleaner air. Complete combustion will reduce drastically the production of particulate matter. This email address is being protected from spambots. You need JavaScript enabled to view it.

GTI2016: Filling in the missing link on combustion monitoring between laboratory and real gas turbine

Meggitt Sensing Systems and Combustion Bay One work together on monitoring of combustion dynamics in gas turbines. The latest progress will be presented at the conference GTI2016 in Berlin (presentation no. 026). This presentation focuses on the latest efforts made to automate the recording and documentation of even small changes of the burner operation conditions, and correlate these to the dynamic measurements.

Date and location: GTI2016, Berlin, Thursday 29th September 2016 at 11:30 

The focus is put on the precise combustion control using CBOne's burner test rig and methods, and detailed description of the latter using MSS' measurement chain including fast-pressure sensors and accelerometers, as well as associated data acquisition systems.

See, size and seize the flame: the emotion project

Combustion Bay One.e.U. works currently in co-operation with FH Joanneum/Aviation on the development of an embedded optical sensor for real-time monitoring of the flame condition in aeroengine combustors.

This feasibility study is financed by the Take-Off programme from the Austrian Research Promotion Agency (FFG).



The very promising first results will soon be presented at the following conference:

Kraft, G., Giuliani, F., Pfefferkorn, L. and Andracher, L.
Toward embedded optical measurement techniques for precision combustion monitoring in aeroengines
Proceedings of the XXIIIth Biannual Symposium on Measuring Techniques in Turbomachinery
Stuttgart, Germany,1 - 2 September 2016

The Strings of Fire

Combustion Bay One worked together with Meggitt Sensing Systems (MSS) on an Applied Research & Development programme for precision monitoring of gas turbine combustion.

An original methodology for gas turbine combustor characterisation and monitoring was developed, using MSS' instrumentation and CBOne's siren pulsator. Experiments with combustion were performed on CBOne's test bench at FH Joanneum, Graz, Austria. The results are published in a joint article to be presented at the ASME Turbo Expo in Seoul, South Korea, 13-17th of June 2016.
