摘要
中等规模的生物质气化发电技术 (1- 5 MW) ,现阶段在我国具有特别重要的意义。从系统匹配的角度 ,阐述了中型生物质气化发电系统中气化炉、净化系统及内燃机三部分的相互关系和设计要点 ,指出 40 0 k W以上发电系统最好选用循环流化床气化炉。以用谷壳做原料的“1MW生物质气化发电系统”为基础 ,讨论系统设计和运行中的关键。结果表明 ,气化炉操作温度在 70 0 -80 0℃之间 ,系统运行基本平稳 :当负荷超过 75 0 k W时 ,系统接近最佳运行点。同时指出 ,为进一步完善系统 ,提高市场竞争力 ,焦油裂解技术 ,适于联网的 5 0 0 k W以上内燃机组是亟待解决的技术关键。
Concurrently this paper poins out that the Circulating Fluidized Bed Gasifier(CFBG)is an optimal choice in system with capacity above 400kW.Further,based on the design principle and practical running parameters of“1MW BGPG System”,it is found that the system operation is stable at temperature from 700℃to800℃,and gradually reached its optimal condition while the load being increased above 750kW.Key techniques such as tar cracking and large size gas engine with 500kW or above etc.are expected to be solved urgently so as to promote its business application.
