摘要
摘要 本文介绍了通过蒸汽射流雾化柴油燃料燃烧的实验研究结果，以及在不同温度的燃烧室供气条件下混合区和气体生成区的燃料存在情况。研究的目的是开发一种用过热蒸汽喷射雾化液态碳氢化合物燃料的燃烧方法，作为提高燃烧效率和降低燃烧产物中有害物质含量的一种可行方法。当一次空气温度升高到 200° 时，发现火焰温度升高，这导致燃烧产物中 CO 浓度降低，NO(_{\rm x}\)含量升高。在这一数值之后，没有观察到有害物质含量的变化，这可能是由于供气的热量使气体发生室中的燃料完全蒸发所致。
Experimental Study of Influence of Initial Air Temperature on Characteristics of Combustion of Diesel Fuel Atomized by Jet of Superheated Steam
This paper presents the results of an experimental study of combustion of diesel fuel at atomization by a steam jet and fuel presence in the mixing and gas generation zone at different temperatures of the air supplied to the burner chamber. The research aim is to develop a method of burning liquid hydrocarbon fuel atomized by a jet of superheated steam as a promising approach to increasing the combustion efficiency and reducing the content of harmful substances in combustion products. When the temperature of the primary air was increased to 200°, the flame temperature was found to grow, which led to reduction of the concentration of CO in the combustion products and increase in the NO\(_{\rm x}\) content. After this value, no changes in the content of harmful substances were observed, which is probably due to the complete evaporation of the fuel in the gas generation chamber due to the heat of the supplied air.
期刊介绍：
Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
