The performance and emission levels of a 160 N (35 lbs) thrust gas micro-turbine, running on blends of kerosene and waste cooking oil (methyl ester), were investigated over the take-off, cruise and idle phases of a typical flight profile. We considered three blends with biofuel volume fractions of 15%V (B15), 30%V (B30) and 90%V (B90). Relevant quantities such the thrust, the specific fuel consumption (SFC), the exhaust gas temperature (EGT), the unburned hydrocarbons (HC), and the production of O2, CO, CO2, NOx, were analyzed. Their time-weighted behavior was then plotted as a function of the blend type. It was found that an optimal fuel blend may be approximately defined by the equilibrium between two main contending factors: a) the production of thrust, and b) the amount of gas emissions. Also, it was observed that low blends (e.g. B15) produced thrust and SFC levels similar to those of kerosene, while high blends (e.g. B90) significantly reduced the gas emission levels at the expense of thrust production.

使用生物燃料混合物的微涡轮特性和排放

在典型的飞行剖面的起飞,巡航和怠速阶段,研究了运行于煤油和废烹饪油(甲酯)混合物中的160 N(35磅)推力气体微型涡轮的性能和排放水平。 。我们考虑了三种混合燃料,其中生物燃料的体积分数分别为15%V(B15),30%V(B30)和90%V(B90)。相关推力,比燃料消耗(SFC),排气温度(EGT),未燃烧的碳氢化合物(HC)以及O 2,CO,CO 2,NO x的产生等相关量,进行了分析。然后将其时间加权行为绘制为混合类型的函数。已经发现,最佳的燃料混合物可以大致由两个主要竞争因素之间的平衡来定义:a)推力的产生,b)气体排放量。此外,还观察到低混合气(例如B15)产生的推力和SFC含量与煤油相似,而高混合气(例如B90)则显着降低了气体排放量,但以推力产生为代价。
