Abstract

The energy and natural resources being increase due to the growth economic and attention together with the alternative fuel. As one of different solution to these problems, emulsion fuel technology in biodiesel has received close attention because it may provide better combustion efficiency and would contribute to a reduction in emissions, such as nitrogen oxides (NOx) or particulate matter (PM). This solution of this issue is by using biodiesel fuel as an alternative fuel from Crude Palm Oil (CPO). CPO is one of the most economical options for producing biodiesel due to the biodegradable properties and preserves energy. This study focuses on the observation of ignition and combustion characteristics of biodiesel-water-air rapid mixing of biodegradable fuel using internally rapid mixing injector in burner combustion. In these experiments, biodiesel fuel derived from the crude palm oil were used in the same nozzle ? = 50° characteristics of burner system. This study focuses on the observation of the real images of the spray characteristics together with equivalence ratio, water content, spray penetration length, spray angle and spray area. Water emulsion of percentage up to 15vol% and blending of biodiesel ratio was varied from 5vol%- 15vol%. The diesel fuel has been compared with based analyzed of real spray images with the times change. The results show the percentage of biodiesel and shows the higher of water content due to the higher viscosity affects.
