燃无烟煤低倍率循环流化床锅炉

Low Circulating Ratio CFB Burning Anthracite Coal

介绍了 DHCF2 5 / 3.82 - 45 0 - W 燃福建无烟煤循环流化床锅炉的设计要点 ,即采用低倍率循环、中温旋风分离器和分级燃烧等设计思想来设计该锅炉。锅炉的运行测试结果表明 ,该锅炉具有 10 %超负荷能力 ,在额定负荷时 ,热效率达81.13%。表明低倍率循环流化床锅炉是解决难燃无烟煤的较好出路。

This paper introduced a kind of CFB boiler burning FuJian anthracite coal.The design characteristics are low circulating ratio,medium temperature cyclone separator.and staged combustion.The performance tests showed that the maximum steam output of this CFB boiler could exceed 28t/h,and thermal efficiency reached 81.13% at full load.It successfully resolved the low rank anthracite coal combustion.
