ASME Turbo Expo 2017: Make Combustion Great Again!!!!

We are honoured to be part of the renowned ASME Turbo Expo 2017. This year's ASME conference will be held from June 26 - 30 in Charlotte, North Carolina. CBOne will present its latest research about a novel probe concept for advanced combustion monitoring and about a method for the improvement of impaired combustion conditions at off-design operation points.

Charlotte likes it hot !!!

For the improvement of impaired combustion conditions a robust acoustic driver (called siren) is used, being able to perform well and last long in an industrial environment. The previous figure suggests how the siren could be implemented on a real power gas turbine.

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.

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!

Variable geometry burner for an extended combustion range (ASME Turbo Expo 2012)

The motivation is to produce a flame with extended combustion range compared to conventional, with the possibility to optimise the ratio between thermal power and gaseous emissions. As an alternative to staged combustion, variable geometry offers in theory the advantage of a much more compact burner. We assessed this technology.

The results were presented at the ASME Turbo Expo 2012 in Copenhagen.
