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

You have the fuel, we have the spark! Combustion Bay One is an engineering office specialised in advanced combustion management, situated in Graz, Austria.
Less fuel consumption, less pollutant emissions, more flexibility, more safety for your thermal facilities.
The name Combustion Bay One highlights the idea of experimental facilities towards a better combustion. In short CBOne.
Research and Development is our key asset at CBOne. Some call it the Combustion Engineering. Some clients call it our Magic. We name it our job.
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 aeroenginesProceedings of the XXIIIth Biannual Symposium on Measuring Techniques in TurbomachineryStuttgart, Germany,1 - 2 September 2016
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.

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.
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.
