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及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并实现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及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及终端应用的影响规律，对使用掺氢天然气作为燃料所带来的机遇与挑战进行了概述。【结果】对于现有天然气燃气设备来说，还需通过气体互换性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CO2排放，然而掺氢带来的火焰温度升高与产生更多的OH自由基、H自由基这两方面会分别对氮氧化物的生成起促进与抑制作用，因此掺氢对NOx的影响并不确定。此外，掺氢还可能导致燃烧器回火甚至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及低污染排放，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。
Abstract:
【Objective】The extensive use of fossil fuels around the world has caused serious environmental pollution and climate change, hydrogen is considered as one of the significant energy carriers in the future. From the perspective of economy and technical feasibility, hydrogen-blended transportation and terminal hydrogen-blended combustion using natural gas pipeline network is one of the effective ways to achieve the dual-carbon goal in the gas field.【Method】To study the effect of hydrogen blending on gas characteristics and terminal equipment operating conditions, the research status of hydrogen-blended natural gas combustion technology at home and abroad is investigated in this paper from the aspects of gas interchangeability, combustible range, combustion characteristics, emission characteristics and terminal applications, and the research results of different scholars are summarized and compared. The influence of hydrogen-blended on fuel combustion and terminal applications is described in detail, and the opportunities and challenges of using hydrogen-blended natural gas as fuel are summarized.【Results】The results show that for existing natural gas appliances, hydrogen availability needs to be accurately evaluated through gas interchangeability. The characteristics of hydrogen-blended gas, such as wide combustible range, fast combustion speed and short ignition delay time, have obvious promoting effect on combustion. In terms of emission characteristics, CO and CO2 emissions can be reduced by mixing hydrogen. However, the increase of flame temperature brought by mixing hydrogen and the generation of more OH free radicals and H free radicals will promote and inhibit the generation of nitrogen oxides, respectively. Therefore, the influence of mixing hydrogen on NOx is uncertain. In addition, hydrogen mixing may also lead to safety problems such as burner tempering and even fuel explosion.【Conclusion】How to achieve efficient and stable combustion of hydrogen-blended natural gas and low pollution emission while ensuring combustion safety is an important challenge faced by the large-scale application of hydrogen- blended natural gas combustion technology.
