由于石油燃料价格不断上涨和化石燃料供应来源有限，全球对可再生燃料来源的兴趣推动了对替代和可持续燃料的研究，应该找到和开发这种燃料。改进工作的重点是在不牺牲可靠性的情况下减少排放、提高效率和降低成本。马来西亚拥有丰富的棕榈油生产，棕榈油作为混合生物燃料可能是化石柴油的潜在替代品。在发达国家，生物燃料已用于柴油发动机、锅炉和燃气轮机，而未对其系统进行重大改造。在水冷式连续喷雾燃烧装置上研究了棕榈油在柴油中的混合燃烧特性。分析了生物质燃料各种混合燃料的理化特性。在燃烧装置上进行了棕榈油在石油柴油中体积掺混比例为10%、20%和30%的试验，并在较宽的空燃比范围内进行了试验。混合燃料对燃烧效率、烟气温度和排放有影响。将结果与100%柴油的基线燃料进行比较。结果发现，高达20%的油精的混合燃料在火焰长度、火焰稳定性和排放方面与柴油燃料具有可比性。
Global interest in renewable source of fuels caused by the escalating price of petroleum fuels and finite source of fossil fuel supply, drive the search for an alternative and sustainable fuels which should be found and developed. Improvement efforts focus on reducing emissions, improving efficiency and lowering costs without sacrificing reliability. Malaysia with abundant of palm oil production, the use of palm oil as blended biofuel could be the potential substitution for fossil diesel. Biofuels have been used in diesel engines, boilers and gas turbines in developed countries without major modification on their system. This paper reports a study on combustion characteristics of blended palm olein in diesel in a water-cooled continuous spray combustion unit. The physical and chemical characteristics of the various blends of biofuels were given and analyzed. The different blending ratios of palm olein of 10%, 20% and 30% in petroleum diesel volumetrically were tested in the combustion unit over a wide range of air fuel ratio from rich to lean. The blended fuels give effect to the combustion efficiencies, flue gas temperatures and emissions. The results were compared to the baseline fuel which is 100% diesel. It was found out that the blended fuel of up to 20% olein gives comparable results as diesel fuel in term of flame length, flame stability and emissions.
