Selection of slag conveying system of CFB boiler

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.
