摘  要:随着经济和社会的发展,国家对能源的需求量越来越大,这与化石能源短缺、环境污染、温室效应等问题相矛盾,因此寻找高效清洁的替代燃料势在必行。氨的体积能量密度较高、成本低且完全燃烧时产物的污染性小,具有成为新时代绿色能源的潜力。但它的燃烧性能较差,通常需要掺混煤、CH_(4)和合成气等燃料来改善。本文主要介绍了含碳掺氨的煤掺氨和甲烷掺氨混合燃料在基础燃烧特性和燃烧应用优化方面的研究进展。总结了不同燃烧策略及燃烧器设计中掺混氨燃料的燃烧特性和排放规律,为未来工业化应用研究提供一定的参考。但在实际应用氨燃料过程中仍存在不少挑战,未来可进一步对优化分级燃烧的策略、改善相关燃烧设备的结构、调整含氨燃料的喷射方式等方面进行研究,以实现高效低污染氨燃料的应用目标。Fossil fuels meet most of the world’s energy demand today.But too much use of conventional fossil fuels is causing many severe problems,such as environmental pollution,global warming and energy crisis.Therefore,looking for environmentally friendly fuels is very necessary.Ammonia has attracted more and more attention because it is a carbon free carrier with advantages of high energy density and low cost.However,ammonia usually need to co-fire with some fuels such as coal,CH_(4) and syngas to improve the combustion characteristics of pure ammonia.This article introduces a detailed development of ammonia/coal and ammonia/methane as fuels for main applications such as boiler and gas turbine.It summarizes the fundamental combustion characteristics and the application research progress of ammonia blends.What’s more,the current understanding of combustion characteristics and the emission characteristics are also summarized.However,using ammonia blends as alternative fuels still has many challenges.In future,the improvement of combustion strategies,equipment and injection strategies is very urgent in order to apply ammonia as a practical fuel with high efficiency and low emission.
