Combustion Optimisation / Advanced Fire Management: CBOne

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:

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.

MethaNull at EnInnov 2016: same power, 2% less consumption and CO2, 15% less other pollutants

(conference talk)

The COP21 conference in Paris, December 2015, made decisions about keeping the temperature rise below 2 degrees. This implies more sustainable resources and a rationalisation on our use of conventional energies. One option is better combustion technologies.

In 2012, CBOne announced the start of the programme MethaNull. Based on a flexible on-off pulse combustion technology, simultaneous decrease in consumption and in pollutant emissions should be made possible. We worked on this technology demonstrator intensively 2013-2015 with the support of the AWS / PreSeed grant. Today we are proud to announce: it works!

Laboratory testing showed that at the same fuel consumption, MethaNull technology versus conventional provides the following figures: +2% in outlet temperatures were observed, for -15% NOx and -13% CO emissions. Machine warm-up is accelerated with a 1.1 factor. Operation is extended down to 90% fuel consumption of the conventional lean blow out limit.

MethaNull means less CO2

The project MethaNull II comes to an end when the conference in Paris, the COP21 starts. The quantitative results will be published in June 2016. One thing must be known: our technology allows to extract more heat from a given amount of fuel compared to conventional. Or it is possible to generate the required amount of energy and save fuel, hence produce less CO2 with our technology. Combustion technologies can be improved - and we did it. This is important.
