生物质油-柴油超声波乳化液燃烧性能研究

Combustion Property of Bio-diesel Fuel Produced by Phacoemulsification

利用自行研发的槽式可变频率可控波形超声波乳化仪,将一定体积比的生物质油与0#柴油在加入少量乳化剂(Span 80、Tween 80)的情况下进行超声乳化,制取了可直接用作柴油机燃料的生物油-柴油超声波乳化液,并进行了柴油机应用台架试验,试验结果表明:与柴油相比,生物质油-柴油超声波乳化液的NOX排放大幅度的降低,其中小负荷时NOX排放较柴油低50%左右;不同配比的乳化液(B10、B15、B20)炭烟排放均比0#柴油排放低,烟度排放值K小于1,远低于国家标准(K<3)。

Using the variable frequency controlled waveform ultrasonic emulsification device, emulsion of 20 % bio-oil with diesel by adding a little emulsifier （Span 80 and Tween 80） was used to produce the emulsified bio-diesel. Experiment showed that it can be used directly in diesel engine. The result of the experiment showed that the NOx emissions significantly reduced 50% lower than that by diesel. The smoke of B10, B15, B20 are all obviously lower than 0# diesel. The emission number for smoke ＂K＂ are all no more than 1 and far below the national standard （K 〈 3 ）.
