Abstract
Relevance. The greatest effectiveness in determining the main characteristics in gas burning was shown by optical methods due to their high speed and accuracy. Despite all the advantages of these methods, their main disadvantage is the price and folding of implementation. Therefore, today it is necessary to improve approaches to solve this problem.
Purpose. The research is devoted to the study of diffusion flame by a semi-empirical method.
Methods. The data of the experimental study of the diffusion flame of hydrocarbons on the example of propane are presented. To visualize the invisible part of the structure of this flame, namely, the afterburning zone of hydrogen molecules formed in the flames in nonequilibrium quantities and, due to the large value of the diffusion coefficient, leaving the flame zone and creating a new combustion zone, molecules containing atoms of alkali metals (NaCl and Na2CO3) are vaporized in the flame zone.
Results. The method of delivery of molecules of alkali metal salts from outside was applied for the first time, which allowed the investigation of this phenomenon more thoroughly. Based on the research results, a method for determining the concentration of hydrogen atoms and the relative distribution of the concentration of hydrogen molecules along the axis of propagation of the flame after the burning zone was proposed. The research method combines experiments with mathematical modeling. The application of the method described in the article makes it possible to determine the distribution of hydrogen molecules over the glow zone of the main fuel.
Conclusions. The results obtained will help to better understand the phenomena of hydrocarbon combustion under diffusion flame conditions, as well as to search for new ways of obtaining hydrogen fuel from domestic waste treatment
