摘要
氨(NH3)是一种不含碳的携氢燃料,易制备且燃烧不产生CO2,热解脱氢所需的能量低,与碳氢燃料(如柴油)融合燃烧时,可以达到提高燃料能量利用率及减少温室气体排放的目的.本文阐述了目前氨能融合燃料发展的必要性,对常用的氨能融合燃料(氨—氢气、氨—甲烷和氨—柴油)内燃机发展中面临的如稳定性差、燃烧慢和着火难等挑战,提出了优化氢气掺杂比例和燃烧室设计、低温脱硝、调整氨占比和富氧环境等对策,并对氨能融合燃料未来的发展进行了展望.
Abstract
Ammonia(NH3)is a carbon-free hydrogen carrier fuel that is easy to produce and does not generate CO2 when burned.The energy required for its thermal decomposition and hydro-gen release is low.When co-fired with carbon-based fuels(such as diesel),it can improve the fuel energy efficiency and reduce greenhouse gas emissions.This article discusses the necessity of developing ammonia-blended fuels,the challenges faced in the development of ammonia-blended fuels(ammonia-hydrogen,ammonia-methane,and ammonia-diesel)in internal combustion engines,such as poor stability,slow combustion,and ignition difficulties.It proposes solutions such as optimizing the hydrogen doping ratio,improving combustion chamber design,low-tem-perature denitrification,adjusting the ammonia proportion,and creating an oxygen-rich environ-ment.The article also looks ahead to the future development of ammonia-blended fuels.
