摘要

本實驗主要以霧化噴嘴搭配不同駐焰器，以柴油、生質柴油為主要油料，觀察各種油料之霧化燃燒現象，在火焰長度、焰色上各種不同組份油料之比較，再將柴油與水、柴油與乙醇、生質柴油與乙醇製作成油水乳化液，觀察在同樣噴霧燃燒條件下預混油料不同所造成燃燒現象差異。

在添加乙醇後火焰呈現貧油燃燒的反應會提前發生，而火焰長度隨著空氣量的加大呈現變短的趨勢，添加水後火焰呈現因大量CO2及H2O所產生的紅焰現象，混合易揮發易燃燒組份油料時，較高的駐焰器有較好的燃燒效率，混合不易揮發不易燃燒組份油料時，較低的駐焰器有較好的燃燒效率。

The spray nozzle with different frame holders and fuels are investigated. The experimental are mainly compose of Diesel and Bio-Diesel and the frame status such as color and length are fully studied. The results show that even in the same experimental environment, the distinct emulsion such as Diesel, Bio-diesel, water, and ethanol would lead to various spray combustion phenomena.
These findings also reveal that the high frame holder will promote combustion efficiency with the fuels which tend to evaporate and burn. Otherwise, the low high frame holder will increase the combustion ability with the fuels which are hard to vaporized and ignited.
