摘要

本文介绍了天然气层流预混火焰中水分对二氧化氮形成和NO氧化为NO2影响的实验研究结果。在燃烧过程中，水蒸气与燃料和氧化剂一起是第三个非常有影响力的参与者。由于在燃烧过程中插入了额外数量的HO2-和OH-自由基，将水分注入燃烧区会产生影响，这有助于强化NO氧化为NO2。在燃烧过程中引入了“过量水分比”的概念。这些研究是在实验室装置中进行的，条件是在横向圆柱形钢稳定器后面形成天然气的V形层流火焰，并确定烟气成分的浓度。

EFFECT OF MOISTURE ON NITROGEN DIOXIDE FORMATION IN LAMINAR FLAME OF NATURAL GAS

The paper contains the results of experimental studies of the effect of moisture on nitrogen dioxide formation and on oxidation of NO to NO2 in laminar premixed flame of natural gas. The water vapor is shown to be the third very influential participant, along with fuel and oxidizer, in the combustion process. Injection of moisture into the combustion zone has an effect due to the insertion of additional quantities of HO2- and OH– radicals into the process, which contributes to the intensification of the oxidation of NO to NO2. Introduction of the concept of the “excess moisture ratio” in the combustion process is proposed. The studies were executed at the laboratory installation in conditions of formation of the V-shaped laminar flame of natural gas behind a transverse cylindrical steel stabilizer, with determining the concentrations of flue gas components.
