Development of Modern and Efficient Combustion technologies


Abstract : Flameless combustion represents a very attractive solution for combustion systems as it can provide high combustion efficiency with low NOx and soot emissions. The increasing interest in flameless combustion is also motivated by its large fuel flexibility, representing a valuable technology for low-calorific value fuels, high-calorific industrial wastes and hydrogen-based fuels. Moreover, coupling flameless combustion with oxy-fuel technology is extremely appealing for the steel industry, to increase the fuel flexibility and to reduce fuel consumption and pollutant emissions. Flameless combustion still appears worthy of investigations and attention. In particular, the fundamental mechanism of the interaction between turbulent mixing and chemical kinetics needs to be elucidated. With respect to conventional flames, the turbulence levels in flameless combustion are enhanced, due to flue gases recirculation, thus reducing mixing timescales. On the other hand, chemical timescales are increased, due to the dilution of the reactants. Hence, the turbulent and chemical timescales are of the same order of magnitude, thus leading to a very strong coupling. Subsequently, combustion models should take into account both mixing and chemical kinetics, leading to a very challenging task. The present project aims at developing predictive simulation tools for flameless and oxy-flameless combustion technologies.
