摘要
本文主要论述了自主研发的3000kW生物质锥形流化床气化发电机组工程,对气化发电系统的工艺过程、设备设计要点及系统运行情况分别进行了阐述。研究设计的气化发电系统工程运行结果表明锥形流化床气化炉操作弹性大,分布锥结构很好地改善了气体分布状况,最佳气化温度为710～740℃。系统运行数据表明:生物质耗量为1.77kg/kWh,每公斤稻壳产气为1.62Nm3,系统总效率为15%,发电机转化效率25%。
This paper introduces a 3000 kW independent R ＆ D biomass gasification-based power system using cone-shaped fluidized bed, including the technological process, system design, and operating performance. Results show that the cone-shaped fluidized bed gasifier is very flexible in operation, and the distribution cone well improves gas distribution. The optimal gasification temperature is 710 -740 ℃. The wastage is 1.7 kg/kWh, yield is 1.62 Nm^3/kg, system efficiency is 15 %, generating efficiency is 25 %.
