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.
為瞭提高循環流化床( CFB)鍋爐底渣輸送繫統運行的經濟性和安全性,從技術分析以及實際運行情況上,對大型CFB鍋爐底渣輸運方式進行比選. 通過分析CFB鍋爐輸渣繫統的工作原理,對埋颳闆機輸渣繫統和大傾角帶式輸送機輸渣繫統的技術運行特點進行瞭比較. 結果錶明,埋颳闆輸渣繫統的結構較為複雜且運行維護工作量大,繫統運行風險也較大;帶式輸送機輸渣繫統的結構相對簡單且運行維護工作量小. 對于新建CFB鍋爐機組,建議採用帶式輸送機輸渣繫統.

In order to improve economic benefits and safety of slag conveying system of CFB boiler,the slag conveying methods were ana-lyzed 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 new-ly constructed units,the system of belt was the better choice.
