内循环流化床循环流率预测模型及试验验证
摘要
提出了终端速度法和滑移系数法2种内循环流化床循环流率的计算模型
并搭建了内循环流化床试验台
利用容积测量法得到循环流率试验值。对比模型预测值和试验值
发现以滑移系数计算颗粒相速度的模型预测值与试验值较吻合。
Abstract
Two circulating flow rate calculation models for internally circulating fluidized bed(ICFB)boiler were proposed
namely terminal velocity method and slip coefficient method.Moreover
a test bench was set up
using volumetric measurement method to obtain the circulation flow rate of the test system.Comparison between the predicted value and test value shows that the value predicted by the slip coefficient method agrees well with the test value.
