生物质灰熔融特性调控的研究进展
|
摘要
生物质灰熔融特性是生物质转化(燃烧和气化)过程中判断结渣的重要指标。在分析生物质灰熔融特性调控重要性的基础上,对添加剂、生物质添加和配煤等方式对生物质灰熔融特性的影响规律和机制进行了较为系统的阐述,最后对生物质灰熔融特性调控的研究方向进行了展望。
The biomass ash melting is an important indicator to determine slagging during the process of biomass conversion( combustion and gasification). On basis of the discussion of importance of biomass ash fusion characteristics( AFC) regulation,the effects of additives,co-firing biomass and coal blending on the AFC of biomass are discussed,and a outlook on the important research directions of biomass AFC was proposed.
