摘　　要：生物质与煤混燃较纯生物质或纯煤燃烧具有更为广阔的发展前景,对改善煤炭利用、减轻环境污染具有积极意义.为了全面了解和分析生物质与煤混燃过程中生成的可吸入颗粒物PM10的研究现状与发展趋势,以实现颗粒物减排目的,系统综述了生物质与煤混燃颗粒物的排放规律,重点阐述了混烧过程中PM10的排放特性、影响因素及形成机制,并进一步分析其化学组成、性质及痕量元素的分布.最后提出了生物质与煤混燃研究领域存在的问题及发展方向,以期对生物质与煤混燃过程中颗粒物的减排与控制提供参考与借鉴.Compared with pure biomass or pure coal combustion,the co-firing of biomass and coal has a broader development prospect,which is of significance to the coal utilization and environmental pollution alleviation.To fully understand and analyze the current status and development trend of the inhalable particulate matters(PM10)formed in the co-firing of biomass and coal so as to realize the emission reduction target,the emission characteristics of particulate matter from the co-firing of biomass and coal are summarized systematically.The emission characteristics,influencing factors and formation mechanism of PM10 formed in co-firing are discussed in detail.In addition,their composition and properties and the distribution of trace elements are further analyzed.Finally,the existing problems in the co-firing of biomass and coal and the development trend are proposed,which may provide reference for the emission reduction and control of particulate matters.
