摘　　要：在当前全球致力于实现碳达峰与碳中和的“双碳”目标背景下,如何高效提升可再生能源的利用比例,逐步减少对煤炭等传统化石能源的依赖,已成为世界各国能源战略转型的关键议题。生物质能源,作为一种潜力巨大的可再生资源,因其总量丰富、来源广泛、易于存储与运输的特点,在推动能源结构绿色转型中扮演着重要角色。若将生物质能源与燃煤锅炉进行大比例耦合利用,可减少温室气体、氮氧化物、硫氧化物等环境污染物的排放。生物质燃料因其挥发分含量高、反应活性强、灰分和硫含量较低的优势,使其不仅能作为直燃耦合的原料,而且也能在气化后与煤粉耦合燃烧。无论是采用生物质直燃耦合发电技术还是生物质气化耦合燃烧发电技术,由于需要更新的设备较少、燃料资源利用率较高,已成为传统火力发电厂典型的低碳转型方向。从我国生物质资源量和利用情况出发,系统梳理了生物质与煤粉直燃耦合发电技术研究现状以及生物质气化耦合燃烧发电技术研究现状,汇总了生物质与煤粉直燃耦合以及生物质气化耦合燃烧的污染物排放、积灰、结渣以及腐蚀等方面的研究,并总结了生物质耦合燃烧发电现有的国内外工程经验,评估了该技术未来的发展趋势。可为生物质能源高效利用和火电行业低碳改造提供理论支撑。Against the backdrop of the current global commitment to achieving the dual-carbon goals of carbon peaking and carbon neutrality,the question of how to effectively increase the proportion of renewable energy and reduce the reliance on traditional fossil fuels such as coal has become a key issue in the transformation of the energy strategies of countries around the world.Biomass energy,as a renewable resource with great potential,has emerged as a promising avenue with its abundant quantity,widespread availability,convenient storage and transportation.The significant coupling of biomass in coal-fired boilers can effectively reduce emissions of greenhouse gases,nitrogen oxides,sulfur oxides,and other pollutants.Additionally,due to the high volatile content,high reactivity,low ash and sulfur element in biomass,it can be used not only as a direct combustion feedstock but also a coupled fuel with coal powder combustion after gasification.Whether adopting the direct combustion coupled power generation technology or gasification coupled combustion power generation technology,the mainstream direction for the transformation of traditional thermal power plants is evident,given the minimal need for equipment upgrades and the high utilization rate of fuel resources.This paper start from the biomass resources and utilization in China,systematically reviews the current research status of biomass and the direct coupled combustion,as well as the gasification coupled combustion,with the focus on the research on emissions of pollutants,ash accumulation,slagging,and corrosion aspects.Further,we summarize the existing engineering project at home and abroad,and make an evaluation of the future development trend of this technology is evaluated.This work will provide theoretical support for the low-carbon transformation of the thermal power industry.
