生物质耦合发电是提高我国非化石能源发电量比例、降低供电CO2排放量的重要发展方向之一。根据国内外生物质耦合发电技术的发展和应用现状,本文总结了直接混燃、间接混燃、并联混燃生物质耦合发电技术的特点、运行经验和影响,并基于生物质耦合发电技术3种方式的特点提出了相应的生物质发电量计算方法。结果表明:在混燃比不大时生物质耦合发电技术的3种方式在安全性上均能够满足工程应用要求,其中直接混燃、间接混燃的能源利用效率高于并联混燃方式;生物质耦合发电技术的3种方式均能准确计算其生物质发电量,生物质发电量的准确计算有助于国内生物质耦合发电技术的推广应用。

Biomass coupled power generation is one of the important development directions for improving the proportion ofnon-fossil energy generation in China and reducing CO2 emissions from power supply.According to the development and application status of biomass coupled power generation technology in China and abroad,this paper summarizes the characteristics,operation experience and influence of direct co-firing?indirect co-firing and parallel co-firing biomass coupled power generation technology.Moreover,based on the characteristics of three ways of biomass coupled power generation technology,the corresponding calculation methods of biomass power generation are proposed.When the co-firing ratio is small,all the above three biomass coupled power generation technologies can meet the engineering application requirements in terms of safety,and the energy utilization efficiency of the direct co-firing and indirect co-firing is higher than that of the parallel co-firing.All the three technologies can accurately calculate the biomass power generation,which contributes to the promotion and application of the domestic biomass coupled power generation technology.
