摘　　要：[目的]化石燃料在全球范围内的大规模使用已带来严重的环境污染与气候问题,氢气因其清洁无污染、来源丰富的特性被认为是未来重要能源载体之一。从经济性与技术可行性角度考虑,利用天然气管网进行掺氢输送及终端掺氢燃烧是实现双碳目标的有效途径。[方法]为研究掺氢对燃气特性和终端用户设备运行工况的影响,从气体互换性、可燃范围、燃烧特性、排放特性、终端应用设备适配性等方面调研了国内外掺氢天然气燃烧技术研究现状,对不同学者的研究成果进行对比分析,阐述了掺氢对燃料燃烧特性与终端应用的影响规律,并阐述了使用掺氢天然气作为燃料所带来的机遇与挑战。[结果]对于现有燃气设备来说,还需通过气体互换性研究开展掺氢燃气的可用性评估。掺氢燃气的可燃范围宽、燃烧速度快、点火延迟时间短等特点对燃烧有明显促进作用。在排放特性方面,可通过掺氢降低CO及CO_(2)排放,然而掺氢会导致火焰温度升高,这在一定程度上会促进NO_x的生成,掺氢同时也产生更多的OH自由基与H自由基以抑制NO_x的生成,因此掺氢对于生成NO_x的影响并不确定。此外,掺氢还可能导致燃烧器回火、燃具爆炸等安全问题。[结论]如何实现掺氢天然气高效稳定燃烧与低污染排放,同时保障燃烧安全,是掺氢天然气燃烧技术大规模应用所面临的重要挑战。[Objective]The extensive consumption of fossil fuels globally has led to significant environmental pollution and climate challenges.Hydrogen is recognized as a crucial energy carrier for the future due to its clean,pollution-free properties and abundant sources.From the perspective of economical efficiency and technical feasibility,transmitting hydrogen-blended natural gas through existing natural gas pipeline networks and facilitating hydrogen-blended combustion in end-user applications offers effective ways to achieve“dual carbon”goals.[Methods]To investigate the influence of hydrogen blending on fuel gas characteristics and operational conditions of end-user equipment,this paper reviews the current research status of hydrogen-blended natural gas combustion technologies in China and abroad.The analysis encompasses multiple aspects,including gas interchangeability,flammable ranges,combustion characteristics,emission characteristics,and adaptability to end-user equipment.Comparative analyses highlight findings from various scholars.The influence patterns of hydrogen blending on fuel combustion characteristics and end-user applications are elaborated.Additionally,this paper summarizes the opportunities and challenges associated with the utilization of hydrogen-blended natural gas as a fuel.[Results]Evaluating the operational availability of hydrogen-blended fuel gas from the standpoint of gas interchangeability is essential for existing natural gas equipment.The characteristics of hydrogen-blended fuel gas,such as wide combustible ranges,high combustion velocities,and short ignition delays,were identified as significant factors in enhancing combustion efficiency.Regarding emission characteristics,hydrogen blending has been shown to reduce CO and CO_(2) emissions.However,the effects of hydrogen blending on NOx emissions remain uncertain due to competing influences:the increase in flame temperature from hydrogen doping promotes NOx formation,while the generation of additional OH and H radicals can suppress it.Fu
