The measurement along a circulating fluidized bed boiler height of the gas conc e ntration and the combustion fraction distribution has demonstrated that the majo r difference between a bubbling fluidized bed and a circulating fluidized one co nsists in their radically different combustion behavior in a dense phase zone.
循环床锅炉沿床高的烟气浓度及燃烧份额分布测试结果证明 ,鼓泡流化床和循环流化床的重要差异表现为密相区燃烧行为的根本不同 ,由于床料平均粒径较低 ,循环床密相区的流动不同于鼓泡床 ,导致气固两相之间的传质阻力增加 ,从而影响燃烧反应 ,密相区的燃烧行为表现为欠氧。
An investigation on the coarse particle flow characteristics and the local heat mass transferbetween gas and solid in the circulating fluidized bed(CFB) was performed.
在不同的表现流速、固体循环率、初始湿含量和颗粒粒径下，沿床高测量了气固相的局部温度，分析和讨论了各种流化参数对传热传质的影响，对粗湿颗粒（Ｇｅｌｄａｒｔ’Ｂ类）循环床提出了一些观点，由此建立的无因次准则方程与实验值吻合较好。
An experimental investigation on the local heat and mass transfer for drying the moist particles in the circulating fluidized bed (CFB) has been performed.
