摘　　要：相较于传统燃烧方式,固体燃料低碳燃烧技术不仅能更好地提升能源的使用效率,还可以在一定程度上减少环境污染。目前较为成熟的固体燃料低碳燃烧技术包括煤掺氨燃烧、煤掺生物质燃烧、化学链燃烧和富氧燃烧。以煤掺氨燃烧的掺氨比、煤掺生物质燃烧的生物质掺混比、化学链燃烧的载氧体及反应条件、富氧燃烧的反应条件及污染物排放等作为切入点,综述了固体燃料低碳燃烧技术的发展现状,并对其未来的发展进行了展望。对比不同形式煤燃烧的工况,发现掺氨比、生物质掺混比对煤燃烧过程氮氧化物排放量影响较大,甚至会影响锅炉的运行环境和整体效益。化学链燃烧和富氧燃烧可以提高CO_(2)捕集效率,促进碳的转化,提高氧释放率,进而提高化学反应速率。Compared with traditional combustion methods,solid fuel low-carbon combustion technologies can not only improve energy efficiency,but also reduce environmental pollution to a certain extent.Currently,the mature solid fuel low-carbon combustion technologies include ammonia co-firing with coal,coal-biomass co-combustion,chemical looping combustion and oxygen-enriched combustion.Taking the ammonia mixing ratio of ammonia co-firing with coal,the biomass mixing ratio of coal-biomass co-combustion,the oxygen carrier and reaction conditions of chemical looping combustion,the reaction conditions and pollutant emissions of oxygen-enriched combustion as entry points,the current development status of solid fuel low-carbon combustion technology was summarized and its future development was prospected.Comparing the working conditions of different forms of coal combustion,it is found that the ammonia mixing ratio and biomass mixing ratio have a significant impact on the nitrogen oxides emissions during coal combustion,and even affect the operating environment and overall efficiency of the boiler.Chemical looping combustion and oxygen-enriched combustion can improve CO_(2) capture efficiency,promote carbon conversion,increase oxygen release rate,and thus increase chemical reaction rate.
