摘要
分析了典型的大型循环流化床锅炉炉膛传热数据及其相关参数关系。以12 MW、50MW和135 MW循环流化床锅炉为例,讨论大型循环流化床锅炉炉膛传热问题。此外,还讨论了炉膛悬吊受热面、汽/水冷旋风分离器、外置式换热器和尾部受热面的传热规律,并给出大型循环流化床锅炉传热系数计算的经验公式。
A review literature concerning the heat transfer mechanism and its influencing factors are being presented, together with typical furnace heat transfer data and their dependence on relevant parameters. Taking circulating fluidized bed boilers of 12 MV,50 MW and 135 MW as examples, the heat transfer within the furnace as well as in the heat recovery zone is discussed together with the heat transfer of pendant heat delivery surfaces in the furnace of large circulating fluidized bed boilers and also in steam/water cold cyclone separators. Relevant empirical heat transfer coefficients are being listed. Figs 10,tables 2 and refs 12.
