International Bunsen Discussion Meeting on

Chemistry and Diagnostics for Clean Combustion

21 – 23  June 2017, Bielefeld, Germany

Providing clean(er) energy is one of the grand societal challenges. Today more than 80% of the global primary energy for transportation and power generation involves fossil-fuel combustion, with a slowly increasing fraction of bio-derived fuels. Combustion of fossil fuels increases carbon dioxide concentration in the atmosphere and it leads to undesired pollutants, including especially nitrogen oxides and particulates. Climate effects, poor air quality, and health issues have increased global awareness regarding these emissions. Because of the scale of energy needed, the increase of population and demands of emerging economies, however, it is hard to replace fossil-fuel combustion processes in the short term. Meanwhile fuel efficiency, alternative fuels, the decrease of carbon dioxide emission, and compliance with strict emission standards are the main issues that need urgent attention.

In a discussion-oriented, interdisciplinary approach, this international meeting will focus on some rapidly emerging and particularly timely issues in combustion, including increased efficiency, alternative fuels, and pollutant formation. To understand these issues, knowledge from chemistry, physics, and engineering must be combined from:

Chemistry: because novel fuels and new efficient combustion strategies will lead to different chemical pathways and emissions;

Physics: because chemical pathways and reactive species must be identified and monitored with suitable diagnostics

Engineering: because practical processes define the vastly different boundary conditions.

The meeting thus aimed to provide forefront knowledge from different international foci, to reflect strategies for the future, and to form nuclei for joint research activities. The program composed of invited lectures by eminent international experts as well as contributed talks, selected from submissions, and poster presentations includes ample time for networking and informal exchange. A concluding discussion session was devoted to identify future needs and perspectives.
