【摘要】 本文对温州永嘉生物质中热值气化示范工程系统进行了介绍,并利用该示范工程对木屑热解气化过程进行了研究。结果表明,木屑所产煤气热值可达8～11MJ/Nm~3,属中热值;煤气产率0.27Nm~3/kg以上,平均产气速率可达19Nm~3/h;煤气中焦油含量一般小于50mg/m~3,煤气较为洁净,既可满足民用煤气的热值要求,又可进行燃气发电。最后,利用所产煤气进行了变负载燃气发电实验,实验表明,该煤气品质较高,能够使发电机组连续稳定运行,最大发电效率可达22.16%。更多还原

【Abstract】 A biomass gasification demonstration project with medium calorific value gas supply and power generation in Wenzhou is introduced in this paper. The pyrolysis and gasification process of sawdust has been studied in this demo project. The results indicate that the gas heating value has reached 8～11MJ/Nm~3, the gasification rate is about 0.27Nm~3/kg, the average gas production increases up to 19Nm~3/h and the tar content is below 50mg/m~3. Finally, the power generation tests with several capacities are investigated and the 30kW gas engine can operate steady during the tests.The maximum power generation efficiency can reach about 22.16%.更多还原
