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.
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.

Good Vibes Beat Bad Gas
(conference talk, paper GT2015-42377)
10% less fuel consumption versus conventional for the disposal of gases with low heat value. This was the main result of the MethaNull study presented at the ASME Turbo Expo 2015!
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:
