摘要
为了提高循环流化床(CFB)锅炉底渣输送系统运行的经济性和安全性,从技术分析以及实际运行情况上,对大型CFB锅炉底渣输运方式进行比选。通过分析CFB锅炉输渣系统的工作原理,对埋刮板机输渣系统和大倾角带式输送机输渣系统的技术运行特点进行了比较。结果表明,埋刮板输渣系统的结构较为复杂且运行维护工作量大,系统运行风险也较大;带式输送机输渣系统的结构相对简单且运行维护工作量小。对于新建CFB锅炉机组,建议采用带式输送机输渣系统。
In order to improve economic benefits and safety of slag conveying system of CFB boiler,the slag conveying methods were analyzed from the aspects of technology and practical operation. By analyzing the design mechanism of slag conveying system,the system of burying scraper and belt were compared from the aspects of the characteristics of technology and operation. The results showed that the structure of burying scraper was more complex. The workload of operation and maintenance of burying scraper was heavier. For the newly constructed units,the system of belt was the better choice.
