The air we breathe
A breathtaking picture in the Parisian outskirts during the pollution peak with particulate matter in Dec. 2016
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.
Support CBOne by helping us to promote and deploy our MethaNull technology. We can bend these numbers. We can breathe a cleaner air. Complete combustion will reduce drastically the production of particulate matter. This email address is being protected from spambots. You need JavaScript enabled to view it.

S3R: Safe, Smooth, Smart & Reliable Ignition
If Billy Joel did not make it to start the fire, we did! :)
Ignition is a crucial function in thermal systems. One counts on it when one needs it. This is even more true for set-ups where starts and stops are seldom.
As experts in technical combustion, we happen to have a large experience in ignition. Poor ignition can in the worst case provoke a detonation: the combustor has filled with reactants near the stoichiometry, the energy kernel of the ignition happens to be to high and generates unwillingly a deflagration-to-detonation transition. And boom! And at best the combustor is damaged... This cannot happen. One needs to rely 100% on the ignition, for a smooth and well-controlled start.
In the frame of the emo(o)tion projects, we developed an all-rounder ignition device that connects well with this project because it partly relies on an optical-based flame monitoring. The principle is based on a separated, autonomous premixed flame commanded by a remote central. The device can operate under atmospheric or under elevated pressure conditions. The central can be used for protection, where it prevents the main power source from starting as long as the safe start-up conditions are not reunited, exactly like in a rocket launch sequence.

Solutions for a better combustion
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.
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.
