| 摘 要： | 循环流化床锅炉与鼓泡流化床相比 ,有许多新的特点 ,床内的燃烧和受热面的传热过程很复杂。由循环倍率决定的颗粒浓度是循环流化床锅炉的一个重要参数 ,它对传热强度、燃烧与燃尽、过热器的汽温、负荷的调节范围以及分离器的设计等都产生重要影响。以 65t/h油页岩流化床锅炉的热力计算为例 ,从循环倍率入手 ,着重讨论了循环倍率以及由它决定的飞灰浓度对床内燃烧传热及过热器传热的影响

| Abstract: | Circulating fluidized bed boilers have many new advantages compared with bubble fluidized boiler, and combustion and heat transfer are very complex. Dust concentration in flue gas decided by circulating rate is a vital factor, which effects heat transfer, combustion and combustion efficiency, steam temperature of boiler superheaters, turn down capability and design of separators. Based on the thermal calculation of 65t/h oil shale CFBC, we studies the effect of the dust concentration in flue gas decided by the circulating rate for combustion and heat transfer in bed and heat transfer in boiler superheaters. |
