摘要 通过对型煤锅炉燃用一般型煤及劣质型煤时燃烧特点的对比分析得出型煤锅炉燃用劣质型煤时运行经济性差的结论。燃烧劣质型煤时会造成锅炉热效率降低、出力严重不足、炉膛温度降低、锅炉尾部受热面堵灰腐蚀、增大风机电耗、长期运行可靠性差、司炉劳动强度大等一系列问题。建议型煤锅炉用户选用优质型煤,对锅炉用户自身经济性与保护环境均有好处。 After comparing the combustion characteristics of normal shape - coal and tinpot shape - coal, authors made one conclusion that the shape - coal fired boiler has lower economy when using tinpot shape- coal . It also includes decrease of thermal efficiency, shortage of output, decline of furnace temperature, ash deposite and corrosion of tail heat surface, increase of fan electricity cost, lower reliability of long period running, and bigger stoker labor strength etc. The paper recommends boiler user selecting high quality shape- coal, which is benefit to boiler user's economy and environment protect.
