ERCOFTAC is proud to announce a two day course on Flame Stabilisation for Industrial Burners.
The objective of this 2-day course is to bring the participants to the forefront of modern insights on flame stabilization in industrial burners. Creation of a stable flame always has been one of the design requirements of burners in e.g. furnaces and gas turbines. But the aim to reduce emissions by burning in extremely lean conditions or by exploiting unconventional mixing scenarios has brought the topic of flame stabilization high on the list of challenges in burner design and operation. In this course first an overview of burner types and flame stabilization methods is given, with the underlying design principles and the resulting scaling rules. The required performance of a burner in relation to power, heat flux and emission is put in the perspective of various applications in power generation and petrochemical and metallurgical heating processes. Then modern computational and experimental tools for the investigation of flames are described, with special emphasis on flame stability. Results of the application of advanced CFD methods to real applications will be presented. In a round table discussion the topics of most interest to the participants will be discussed.
The technological challenge is to design a burner with guaranteed ultra-low emissions of NOx, soot and unburned hydrocarbons and with stably burning flames for the whole range of operating conditions. An underlying scientific challenge is the understanding of turbulence-chemistry interaction. Among the questions to be addressed are: Which flow phenomena have the greatest influence on flame stabilization? How are they represented in computational models? What are the essential advantages of large eddy simulation (LES) compared to Reynolds Averaged Navier-Stokes (RANS) simulations? What can we learn from Direct Numerical Simulation (DNS)? What can we learn from advanced laser diagnostics? How far are we in laboratory studies from real scale applications and how far are we in applying our models to real applications? What is the impact of new developments on scaling rules of future combustion systems?
The course is intended for researchers in industry, equipped with a firm basic knowledge in fluid mechanics, heat transport and combustion science, who want to build up or widen their knowledge on modern computational and experimental tools for burner design. Combustion researchers from academia interested in learning more about the opportunities for industrial application are also welcome.
