Combustion Optimisation / Advanced Fire Management: CBOne

Fuel economy, clean energy - MethaNull

Details: Published on Sunday, 11 May 2014 08:00

With the help of the FFG in 2012 and of the AWS in 2013, CBOne started the MethaNull programme (Towards zero Methane emissions in the atmosphere). This technology aims to burn gases with low heat contents under enhanced operation and safety conditions.

Our intention was to provide within a 3-years frame a portable technology based on pulse combustion.

We did achieve our goals.

Perfect burn of gases with low heat contents

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

Details: Published on Friday, 24 March 2017 15:47

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

Details: Published on Saturday, 24 September 2016 16:24

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.

SoTIC 2023: precision monitoring of hydrogen flames (symposium paper)

Details: Published on Wednesday, 06 September 2023 12:38

CBOne will be present at the SoTIC - Symposium on Thermoacoustics in Combustion (11-14 September 2023, ETH Zurich, Switzerland).

Not only are we pleased to be sponsoring the event, but Nina Paulitsch will also be presenting our latest work on hydrogen flames using our Rayleigh Criterion Probe, as part of the BLUETIFUEL project. In short, the RCP combined optical-acoustic probe is perfect for finely monitoring hydrogen flames [Click here for the presentation's slides].
