Purpose

The purpose of this study is to predict the performance and emission characteristics of micro gas turbine engines powered by alternate fuels. The micro gas turbine engine performance, combustion and emission characteristics are analyzed for the jet fuel with different additives.

Design/methodology/approach

The experimental investigation was carried out with Jet A-1 fuel on the gas turbine engines at different load conditions. The primary blends of the Jet A-1 fuels are from canola and solid waste pyrolysis oil. Then the ultrasonication of highly concentrated multiwall carbon nanotubes is carried with the primary blends of canola (Jet-A fuel 70%, canola 20% and 10% ethanol) and P20E (Jet-A 70% fuel, 20% PO and 10% ethanol).

Findings

The consumption of the fuel is appreciable with the blends at a very high static thrust. The 39% reduction in thrust specific fuel consumption associated with a 32% enhance in static thrust with P20E blend among different fuel blends. Moreover, due to the increase in ethanol concentration in the blends PO20E and C20E lead to a 22% rise in thermal efficiency and a 9% increase in higher oxygen content is observed.

Practical implications

The gas turbine engine emits very low emission of gases such as CO, CO₂ and NOx by using the fuel blends, which typically reduces the fossil fuel usage limits with reduced pollutants.

Originality/value

The emission of the gas turbine engines is further optimized with the addition of hydrogen in Jet-A fuel. That is leading to high specific fuel exergy and owing to the lower carbon content in the hydrogen fuel when compared with that of the fossil fuels used in gas turbine engines. Therefore, the usage of hydrogen with nanofluids was so promising based on the results obtained for replacing fossil fuels.

最低排放的可持续航空生物燃料作为 Jet-A 燃料的潜在替代品

目的

本研究的目的是预测由替代燃料驱动的微型燃气涡轮发动机的性能和排放特性。分析了不同添加剂的喷气燃料的微型燃气轮发动机性能、燃烧和排放特性。

设计/方法/方法

实验研究是在不同负载条件下用 Jet A-1 燃料在燃气涡轮发动机上进行的。Jet A-1 燃料的主要混合物来自油菜籽和固体废物热解油。然后用油菜籽（Jet-A 燃料 70%、油菜籽 20% 和 10% 乙醇）和 P20E（Jet-A 70% 燃料、20% PO 和 10% 乙醇）的主要混合物对高浓度多壁碳纳米管进行超声处理）。

发现

在非常高的静态推力下混合燃料的消耗是可观的。在不同燃料混合物中使用 P20E 混合物，推力比燃料消耗减少 39%，静态推力增加 32%。此外，由于共混物 PO20E 和 C20E 中乙醇浓度的增加导致热效率提高 22%，并且观察到更高的氧含量增加了 9%。

实际影响

燃气涡轮发动机通过使用燃料混合物排放非常低的气体，例如 CO、CO ₂和 NOx，这通常通过减少污染物来降低化石燃料的使用限制。

原创性/价值

通过在 Jet-A 燃料中添加氢气，进一步优化了燃气涡轮发动机的排放。与燃气涡轮发动机中使用的化石燃料相比，由于氢燃料中的碳含量较低，这导致高比燃料火用。因此，基于替代化石燃料所获得的结果，将氢与纳米流体一起使用是非常有前途的。
