Abstract

During recent years the increasing consumption of fossil fuel has led to the search for alternative energy. Microalgae emerged as one of the potential sources of Bio-fuels from algae, and it is mostly preferred because it is sustainable and environment-friendly. The oil extracted from spirulina and chlorella microalgae through pyrolysis process at a temperature of 350oC, and the bio-oil properties were analysed. When compared to spirulina bio-oil, the viscosity and density of chlorella bio-oil were very close to the conventional diesel fuel. The Experiment was conducted in a single cylinder four stroke diesel engine for various loading conditions and was carried out for B10 blend for spirulina and chlorella algae bio-fuel, CL10D90 showed maximum output power at 100% load condition has been nearly same for diesel fuel than SP10D90, and the Specific fuel consumption is nearly same when compared with diesel. The Brake thermal efficiency of CL10D90 increases by 4% than SP10 D90 and 2% than diesel, and the combustion characteristic of peak heat release rate is higher and also there is a reduction in HC, CO emission at full load, with slight increase in NOX emission. The experimental result shows that the use of CL10D90 bio-oil in diesel engine is a suitable alternative to diesel.

藻类生物燃料柴油机性能与排放特性的实验研究

近年来，化石燃料消耗量的增加促使人们寻找替代能源。微藻作为藻类生物燃料的潜在来源之一，因其具有可持续性和环保性而备受青睐。以螺旋藻和小球藻微藻为原料，在350℃温度下进行热解提取油，并对其生物油性质进行分析。与螺旋藻生物油相比，小球藻生物油的粘度和密度与常规柴油非常接近。实验在单缸四冲程柴油机上进行，并以螺旋藻和小球藻生物燃料的B10混合燃料为实验材料，结果表明，在100%负荷条件下，CL10D90对柴油的最大输出功率与SP10D90相差不大，比油耗与柴油相差不大。CL10D90的制动热效率比SP10 D90提高4%，比柴油提高2%，峰值放热率燃烧特性更高，满负荷时HC、CO排放降低，NOX排放略有增加。实验结果表明，在柴油机中使用CL10D90生物油是一种合适的柴油替代品。
