人们已经认识到飞灰含碳量是燃煤循环流化床锅炉的重要问题 .它影响了燃烧损失和锅炉效率 .在循环流化床实验台上对六种煤的燃烧进行了研究 ,与燃用相同煤种的循环流化床锅炉的结果比较 ,并与热重分析 (TGA)数据关联 .结果表明 ,飞灰含碳量不仅受运行参数如床温、过量空气系数、配风情况、床存量及床质量的影响 ,而且受煤特性影响 ,煤本身的反应活性是最主要的 .利用热重分析 (TGA)数据可以预测该燃料在循环流化床锅炉燃烧时的飞灰含碳量 . It has been recognized that the carbon content of fly ash is an important issue for coal-fired circulating fluidized bed boilers, which affects the combustion losses and boiler efficiency.In the circulating fluidized bed experimental bench on the combustion of six kinds of coal were studied, The results of CFB boiler with the same kind of coal were compared and correlated with TGA data. The results show that the carbon content of fly ash is not only affected by operating parameters such as bed temperature, excess air ratio, And the influence of coal quality on the coal quality, the reactivity of coal itself is the most important.Using TGA data to predict the carbon content of fly ash in CFB boiler combustion.
