Analysis of superheated steam influence on the content of solid carbon particles during diffusion combustion of liquid hydrocarbon fuel
The study is aimed at clarifying and revealing the basic principles of the effect of superheated steam and its parameters on the content of solid carbon particles (soot) in intermediate and final combustion products when burning liquid hydrocarbon fuel. Using a laboratory atmospheric atomizing burner, it was determined that there is a significant amount of solid carbon particles at the base of the burner flame. When heated air is used instead of steam, an increase in soot content by ∼75 % is observed. The analysis of the flame glow intensity in a narrow ultraviolet band also showed that in air the glow values are ∼75 % higher than when using superheated steam. At the same time, it has been established that the soot content in the final combustion products is affected only by the parameter of the dynamic effect of a jet, which determines air ejection from the environment both into the gas generation chamber and into the external flame region.
期刊介绍：
The journal Thermophysics and Aeromechanics publishes original reports, reviews, and discussions on the following topics: hydrogasdynamics, heat and mass transfer, turbulence, means and methods of aero- and thermophysical experiment, physics of low-temperature plasma, and physical and technical problems of energetics. These topics are the prior fields of investigation at the Institute of Thermophysics and the Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences (SB RAS), which are the founders of the journal along with SB RAS. This publication promotes an exchange of information between the researchers of Russia and the international scientific community.
