宽筛分颗粒对循环流化床锅炉传热的影响

The Effect on Heat Transfer of CFB Boiler With Wide Distributed Particles

文章基于循环流化床的传热特点,应用“分级筛分”和“分级循环倍率”的概念,分析了宽筛分不同粒径颗粒对传热的影响。分别针对密相区,稀相区以及对流受热面的传热进行探讨,对宽筛分循环流化床锅炉的设计和运行有参考价值。

Based on the heat transfer characteristics of CFB and the concept of 'gradation sizing' and 'graded circulatin factor', the effect on heat transfer of wide distributed particles in different size is analyzed, the heat transfer in dease phase area, dilute phase are and convection heating surface is discussed, which has reference value for usisning and operation the CFB boiler with wide distributed.
