柴油发电机组的燃烧的时候,如果不充分的话很容易就会造成大气污染,严重的时候还会危及操作人员的人身安全,柴油发电机厂家今天教大家一些方法改善燃油来降低污染,这个方法就是燃油掺水,燃油掺水的方法有进气管喷水和乳化柴油等,发电机组厂家就这2个方法做出了以下分析:
Diesel generator burning time, if not enough it would be easy to cause air pollution, but also endanger the operator when serious personal safety, the diesel generator manufacturers today teach you some ways to improve fuel to reduce pollution, this method is the method of fuel water, the fuel water intake pipe and water emulsified diesel oil etc. The 2 turbine manufacturers, a method to make the following analysis:
1、进气管喷水
1. Air intake pipe sprinkler
进气管喷水的主要作用是吸热和稀释燃油密度。当少量水进入燃烧室并雾化良好时,由于水蒸气的“微爆”作用使油滴破碎成更小的油滴,因而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最高燃烧温度降低,如水与油混合喷入可降低燃油密度,使最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 effect of the intake pipe water spray is the heat absorption and the dilution of the fuel density. When a small amount of water into the combustion chamber and good atomization, the water vapor of the micro explosion effect of the oil drop is broken into smaller oil droplets, thus promoting 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, as injection can reduce the fuel density mix water and oil, the maximum combustion temperature is further reduced, thus reducing NOx emission. It is necessary to pay attention to the need to prevent freezing in the storage tank of diesel generating sets in winter and to automatically adjust the amount of water spray with the size of the load.
2、乳化柴油
2. Emulsified diesel oil
在柴油中掺水,即乳化柴油,由于其“徽爆”作用,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,乳化柴油可降低最高燃烧温度,因此NOx生成量减少。
Water in diesel oil, the emulsified diesel oil, because of its "Anhui burst" effect, the good fuel atomization well prompted air 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, the emulsified diesel fuel can reduce the maximum combustion temperature, so the production of NOx is reduced.
以上两种做法就是通过对燃油的调整来促进油料的燃烧,燃烧充分之后柴油发电机组排放出的有害气体自然就变少了,对减少环境污染,保障工作环境的安全相当有效。
The above two ways are to promote the combustion of oil by adjusting the fuel oil. After that, the harmful gas emitted from the diesel generating set is reduced naturally, which is quite effective for reducing the environmental pollution and ensuring the safety of the working environment.
