摘　　要：分析总结了不同规模燃烧实验装置所获得O_2/CO_2气氛下煤粉颗粒燃烧的研究现状和研究成果,并对未来O_2/CO_2燃烧技术的发展进行了展望。研究结果表明,在相同O_2浓度下,O_2/CO_2气氛中煤粉燃烧气体和颗粒的温度要比O_2/N2气氛低,并且燃尽时间延长,NOx生成量降低。提出无焰富氧燃烧技术和增压富氧燃烧技术是两种具有较大发展前途的新型燃烧技术。The general research progress and future development on pulverized coal combustion properties in O2 / CO2combustion atmosphere with different scale test rigs were reviewed and prospected. The research results revealed thatpulverized coal particles burned at lower temperatures, endured longer burnout times and released lower NOxconcentrations in O2 / CO2 environment than in O2 / N2 environment with the same oxygen mole fractions. Especially theflameless oxy-fuel combustion technology and pressured oxy-fuel combustion technology were considered as the two newand advanced combustion technologies.
