“双碳”目标下零碳燃料基础燃烧特性实验教学平台开发及应用研究

Study on the Development and Teaching Application of Experimental Teaching Platform for Fundamental Combustion Characteristics of Zero-carbon Fuel

“双碳”目标背景下,为满足燃烧类相关课程实验教学环节的需求,基于氢气预燃室射流点火引燃氨气这一燃烧模式,设计了零碳燃料基础燃烧特性实验教学平台。平台由定容燃烧实验教学平台与光学发动机实验教学平台组成,通过对火焰传播图片与燃烧压力数据的分析实现对不同参数条件下预燃室射流引燃特性和主燃室着火特性的评价。实验教学实践表明,该实验教学平台完全满足零碳燃料基础燃烧特性研究的目标,取得了良好的教学效果。

The combustion characteristics of zero-carbon fuels has become one of the key contents of teaching courses related on combustion.In order to meet the needs of these courses in experimental teaching,an experimental teaching platform for the combustion characteristics of ammonia using hydrogen jet ignition is designed.This platform is mainly composed of a constant volume chamber and an optical engine.The jet ignition characteristics of the pre-chamber and the ignition characteristics of the main combustion chamber under different conditions can be evaluated through the analysis of flame propagation images and combustion pressure data.The practical application results show that the experimental teaching platform can fully meet the objective of researches on the combustion characteristics of zero-carbon fuels,which leads to a pretty good teaching effect.
