柴油发电机组其意义在于提高发电机组操作的安全性和环保性。在研究中 ,燃油掺水经过证实是一个能够改善柴油发电机组污染问题的好方法。下面为大家具体介绍燃油掺水的两种方法:燃油掺水的方法有进气管喷水和乳化柴油等。

The purpose of diesel generator set is to improve the safety and environmental protection of generator set operation. In the study, fuel water was proved to be a good way to improve the pollution of diesel generating sets. Here we introduce specific fuel water two ways: fuel water mixing methods, intake pipes, water jet and emulsified diesel oil, etc..

1、进气管喷水

1 、 intake pipe water spraying

进气管喷水的主要作用是吸热和稀释燃油密度。促进了混合气的形成和燃烧.在燃烧过程中由于水的吸热作用可 使高燃烧温度降低,如水与油混合喷入可降低燃油密度,使高燃烧 温度进一步降低,因此NOx排放减少。需要注意的是柴油发电机组冬季 储水箱需防冻,并要求随负荷大小自动调节喷水量等。

The main function of intake pipe water injection is to absorb heat and dilute fuel density. To promote the formation and combustion of mixed gas. In the combustion process due to the endothermic role of water can make the maximum combustion temperature is reduced, such as water and oil injection can reduce the density of the fuel, the maximum combustion temperature is further reduced, thus reducing NOx emission. It should be noted that the diesel generator sets need antifreeze in winter storage tanks, and require automatic adjustment of water injection with load size.

2、乳化柴油

2 、 emulsified diesel oil

在柴油中掺水,使其燃油雾化 良好,井促使燃烧室内的空气形成强烈紊流,燃油与空气的分布更加均 匀,生成的炭烟减少,水蒸气的水煤气反应也使炭烟排放降低。另外,乳化柴油可降低高燃烧温度,因此NOx生成量减少。

Water in diesel fuel, the fuel atomization is good, well to air the formation of strong turbulence, the distribution of fuel and air is more uniform, the generation of soot reduction, water gas reaction of water vapor also reduced smoke emissions. In addition, emulsified diesel fuel can reduce the maximum combustion temperature, so the amount of NOx production is reduced.
