Incineration is the most common liquid combustible waste disposal method. However, when waste is incinerated, huge amounts of toxic combustion products are formed. The use of steam in the combustion process helps to reduce the toxic emissions. In this work, the effect of steam on the flame characteristics during combustion in a laboratory burner is investigated using diesel fuel as an example. The principle of burner operation is based on liquid fuel spraying by a steam jet as efficient way of liquid combustible waste disposal with heat energy production. The steam gasification of the incomplete combustion products increases the carbon burnout degree and the steam presence in the combustion zone reduces thermal nitrogen oxides formation. Thus, two environmental problems are simultaneously solved: waste disposal and reduction of toxic products. Laboratory experiments were carried out to measure the composition of intermediate combustion products and temperature in the flame of the burner. Comparison of results obtained with steam or air supply under equal conditions showed that the CO content in the regimes with air is 25 % higher than in the regimes with steam; the content of nitrogen oxides in the regime with steam is 30 % lower than in the regime with air.

焚烧是最常见的液体可燃废物处理方法。然而，当废物被焚烧时，会形成大量有毒的燃烧产物。在燃烧过程中使用蒸汽有助于减少有毒排放。在这项工作中，以柴油燃料为例，研究了在实验室燃烧器中燃烧过程中蒸汽对火焰特性的影响。燃烧器的工作原理是基于蒸汽喷射的液体燃料喷射，作为液体可燃废物处理和热能生产的有效方式。不完全燃烧产物的蒸汽气化增加了碳的燃尽程度，并且燃烧区中存在的蒸汽减少了热氮氧化物的形成。因此，同时解决了两个环境问题：废物处理和减少有毒产品。进行了实验室实验以测量中间燃烧产物的组成和燃烧器火焰中的温度。比较相同条件下使用蒸汽或空气供应获得的结果表明，空气条件下的 CO 含量比蒸汽条件下高 25%；在蒸汽状态下的氮氧化物含量比在空气状态下低 30%。
