مطالعۀ سینتیکی اثر اندازۀ ذرات دوده در هم‌سوزی متان-کربن بر مؤلفه‌های سینتیکی و گونه‌های اساسی احتراق

Low radiation intensity heat transfer from methane blue flame has turned into a challenge in industry. The addition of soot into the flame can enhance the radiation. However, the effect of adding soot on chain reaction of methane combustion and NO & CO emissions has not been assessed. Furthermore, one of the most important factors to be considered is the size of the fine particles. Therefore, the chemical kinetics study of the addition of soot and the effect of particles size on methane combustion was studied by EPM method and GRI3.0 mechanism. The results indicated that adding fine particles leads to an increase in adiabatic temperature and NO and CO pollutants. However, large particles vaporize first in the preheat zone and their effects are less significant than fine particles. Also, equivalence ratio was an effective parameter on temperature variation caused by soot addition, and very fine soot particles led to an increase in temperature for all equivalence ratios.
