摘　　要：生物质与煤混合燃烧技术是一种低成本、低风险可再生能源利用方式。依据给料方式的不同,混燃可以分为直接混燃和间接混燃两种方式。受生物质特性的影响,混燃会对原有的锅炉系统产生一定的影响。系统介绍了混燃过程对系统燃烧特性的影响、对SO2、NOx等污染物排放的影响、以及混燃对锅炉系统的积灰、结焦及腐蚀的影响;并在此基础上对混燃的经济性进行了评价,最后给出了目前的混燃研究中存在的问题以及发展的方向。Cofiring of coal and biomass is an useful energy utilization for its low cost and low risk. According to feeding way, it can be divided into direct cofiring and indirect cofiring. Because of biomass particular characteristic, cofiring of coal and biomass would impact on the performance of whole system. The effect of cofiring to whole combustion system is introduced, and contamination status produced by cofiring of biomass and coal is comprehensively summarized, such as SO2, NOx, et al. In particular, the effect of cofiring to ash deposition and fouling and corrosion is analyzed. After that, the economy of cofiring is evaluated. Finally, there are several uncertainties and issues that remain, and which need to be resolved if cofiring is to be expanded.
