Abstract

The invention relates to the technical field of aero-engines, and particularly discloses a dual-fuel energy-saving and environment-friendly aero-engine which comprises a preheating oil tank and a fuel conveying mechanism, and the preheating oil tank is arranged in an annular space formed by radial shrinkage between two stages of centrifugal compressors of the engine; and the preheating oil tank can exchange heat with the annular space, so that the heat of the compressed air in the annular space is utilized to preheat auxiliary fuel such as biodiesel in the preheating oil tank. The fuel conveying mechanism is used for conveying fuel in the preheating oil tank into the annular space so that the fuel can be mixed with the compressed air in the annular space. According to the invention, biodiesel is preheated, atomized, vaporized and mixed with compressed air, so that the purpose of high-efficiency combustion of biodiesel in a combustion chamber is achieved, and biodiesel is successfully used as an auxiliary fuel to be applied to an aero-engine.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a dual-fuel energy-saving and environment-friendly aero-engine. Background technique [0002] The information disclosed in this Background of the Invention is only for enhancement of understanding of the general background of the invention and should not necessarily be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. [0003] With the continuous depletion of petrochemical energy resources, seeking new fuels as available fuels for aero-engines is one of the important research directions for the development of aero-engine technology in the future. At the same time, reducing carbon emissions is also a new challenge for the global energy and power industry in the future. Biodiesel, also known as fatty acid methyl ester, is a general term for soybean oil, rapeseed oil, palm oil and other...
