Abstract

In this work, combustion process of diesel and biofuel blends is studied experimentally in an isothermal oven. Blends with respectively 20%, 40% and 60% of Ethanol (E20, E40, E60), 20%, 40% and 60% of Methanol (M20, M40, M60), and 20%, 40%, 60%, 80% and 100% of Biodiesel (B20, B40, B60, B80, B100), are comparatively analyzed focusing on wall temperature of the isothermal oven and emissions products from combustion. It is found that wall temperature drops with biodiesel content in blends and is higher compared with pure diesel, whatever the content of biodiesel. For diesel-ethanol and diesel-methanol blends the wall temperature is less than pure diesel. Unburned HCs and NOX emissions are very low for all blends and CO emissions increase with higher ethanol and methanol blends. For industrial applications that need high temperature (as drying, cooking, sterilization, others) the combustion of diesel-biodiesel blends are recommended.

生物燃料-柴油混合物在等温烤箱中的燃烧。

本文在等温炉中对柴油和生物燃料混合物的燃烧过程进行了实验研究。对比分析了等温炉壁面温度和燃烧排放产物，分别为20%、40%和60%乙醇(E20、E40、E60)， 20%、40%和60%甲醇(M20、M40、M60)， 20%、40%、60%、80%和100%生物柴油(B20、B40、B60、B80、B100)。结果表明，混合气的壁温随生物柴油含量的增加而降低，无论生物柴油的含量如何，壁温都高于纯柴油。对于柴油-乙醇和柴油-甲醇混合物，壁温低于纯柴油。对于所有混合物，未燃烧的hc和NOX排放量都非常低，而随着乙醇和甲醇混合物含量的增加，CO排放量也会增加。对于需要高温的工业应用(如干燥，烹饪，灭菌等)，建议燃烧柴油-生物柴油混合物。
