循环流化床锅炉尾部对流受热面烟速的优化确定

Gas Velocity Optimization of Heating Surface in the Secondary Pass in a Circulating Fluidized Bed Boiler

尾部对流受热面烟气流速的选取涉及到锅炉整体性能和制造经济性。总结分析了循环流化床锅炉尾部对流受热面烟速的选取原则,在理论分析的基础上,提出了针对新一代循环流化床锅炉的尾部对流受热面烟速的优化确定。

The gas velocity of the convective heating surface in the secondary pass influences the boiler performance as well as the manutac- ture cost. This paper summarizes the analysis of circulating fluidized bed boiler tail convection heating surface flue gas velocity selection principle. On the basis of theoretical analysis, put forward to a new generation of circulating fluidized bed boiler tail convection heating surface flue gas velocity optimization
