Purpose

Diesel has traditionally been considered the best-suited and most widely used fuel in various sectors, including manufacturing industries, power production, automobiles and transportation. However, with the ongoing crisis of fossil fuel inadequacy, the search for alternative fuels and their application in these sectors has become increasingly important. One particularly interesting and beneficial alternative fuel is biodiesel derived from bio sources.

Design/methodology/approach

In this research, an attempt was made to use biodiesel in an unconventional micro gas turbine engine. It will remove the concentric use of diesel engines for power production by improving fuel efficiency as well as increasing the power production rate. Before the fuel is used enormously, it has to be checked in many ways such as performance, emission and combustion analysis experimentally.

Findings

In this paper, a detailed experimental study was made for the use of Spirulina microalgae biodiesel in a micro gas turbine. A small-scale setup with the primary micro gas turbine and secondary instruments such as a data acquisition system and AVL gas analyser. The reason for selecting the third-generation microalgae is due to its high lipid and biodiesel production rate. For the conduction of experimental tests, certain conditions were followed in addition that the engine rotating rpm was varied from 4,000, 5,000 and 6,000 rpm. The favourable and predicted results were obtained with the use of microalgae biodiesel.

Originality/value

The performance and combustion results were not exactly equal or greater for biodiesel blends but close to the values of pure diesel; however, the reduction in the emission of CO was at the appreciable level for the used spirulina microalgae biodiesel. The emission of nitrogen oxides and carbon dioxide was a little higher than the use of pure diesel. This experimental analysis results proved that the use of spirulina microalgae biodiesel is both economical and effective replacement for fossil fuel.

螺旋藻微藻混合物在微型燃气轮机中对发动机性能和排放特性的作用

目的

柴油历来被认为是各个行业最适合、使用最广泛的燃料，包括制造业、电力生产、汽车和交通运输。然而，随着化石燃料不足危机的持续存在，寻找替代燃料及其在这些领域的应用变得越来越重要。一种特别有趣且有益的替代燃料是源自生物来源的生物柴油。

设计/方法论/途径

在这项研究中，尝试在非常规微型燃气涡轮发动机中使用生物柴油。它将通过提高燃油效率和提高发电率来消除集中使用柴油发动机发电的情况。在大量使用燃料之前，必须对其进行性能、排放和燃烧分析等多方面的实验检查。

发现

本文对螺旋藻微藻生物柴油在微型燃气轮机中的使用进行了详细的实验研究。小型装置，配有主微型燃气轮机和数据采集系统和 AVL 气体分析仪等辅助仪器。选择第三代微藻的原因是其高脂质和生物柴油生产率。为了进行实验测试，除了发动机转速在4,000、5,000和6,000rpm之间变化外，还遵循一定的条件。使用微藻生物柴油获得了有利的和预期的结果。

原创性/价值

生物柴油混合物的性能和燃烧结果并不完全相同或更好，但接近纯柴油的值；然而，对于使用的螺旋藻微藻生物柴油来说，二氧化碳排放量的减少是相当可观的。氮氧化物和二氧化碳的排放量比使用纯柴油略高。本实验分析结果证明，使用螺旋藻微藻生物柴油是既经济又有效的化石燃料替代品。
