Purpose

This paper aims to investigate the effect of additives in Jet-A fuel blends, especially on performance, combustion and emission characteristics.

Design/methodology/approach

Jet-A fuel was formed by using Kay’s and Gruenberg–Nissan mixing rules by adding additive glycerol with TiO₂. While measuring the combustion performance, the amount of oxygen content present in fuel and atomization are the key factors to consider. As such, the Jet-A fuel was created by adding additives at different proportion. A small gas turbine engine was used for conducting tests. All tests were carried out at different load conditions for all the fuel blends such as neat Jet-A fuel, G10T (glycerol 10% with 50 ppm TiO₂ and Jet-A 90%), G20T (glycerol 10% with 50 ppm TiO₂ and Jet-A 90%) and G30T (glycerol 10% with 50 ppm TiO₂ and Jet-A 90%).

Findings

From tests, the G20T and G10T produced better results than other blends. The thermal efficiency of the blends of G20T and G10T are 22% and 14% higher than neat Jet-A fuel. Further, the improved static thrust with less fuel consumption was noticed in G20T fuel blend.

Originality/value

The G20T blends showed better performance because of the increased oxygenated compounds in the fuel blends. Moreover, the emission rate of environmentally harmful gases such as NOx, CO and HC was lower than the neat Jet-A fuel. From the results, it is clear that the rate of exergy destruction is more in the combustion chamber than the other components of fuel.

高含氧生物燃料对微型燃气轮机减排的影响

目的

本文旨在研究 Jet-A 燃料混合物中添加剂的影响，特别是对性能、燃烧和排放特性的影响。

设计/方法/方法

Jet-A 燃料是通过使用 Kay's 和 Gruenberg-Nissan 混合规则通过添加甘油和 TiO _{2 形成的}。在测量燃烧性能时，燃料中的氧含量和雾化是需要考虑的关键因素。因此，Jet-A 燃料是通过添加不同比例的添加剂制成的。使用小型燃气涡轮发动机进行测试。所有测试均在不同负载条件下对所有燃料混合物进行，例如纯 Jet-A 燃料、G10T（10% 甘油与 50 ppm TiO ₂和 Jet-A 90%）、G20T（甘油 10% 与 50 ppm TiO ₂和 Jet-A 90%）和 G30T（甘油 10%，含 50 ppm TiO ₂和 Jet-A 90%）。

发现

从测试来看，G20T 和 G10T 产生了比其他混合物更好的结果。G20T 和 G10T 混合物的热效率比纯 Jet-A 燃料高 22% 和 14%。此外，在 G20T 燃料混合物中注意到改进的静态推力和更少的燃料消耗。

原创性/价值

由于燃料混合物中含氧化合物的增加，G20T 混合物表现出更好的性能。此外，NOx、CO 和 HC 等环境有害气体的排放率低于纯 Jet-A 燃料。从结果中可以明显看出，燃烧室中的火用破坏率高于燃料的其他成分。
