| 摘 要： | 为研究电除尘器低低温工况条件下飞灰工况比电阻特性,探讨采用数学模型计算飞灰工况比电阻的可行性,采用BDL型工况飞灰比电阻测试仪对3个典型项目开展飞灰工况比电阻现场在线测定,同时基于R.E.Bickelhaupt模型计算玉环电厂、温州电厂、长兴电厂3个项目飞灰工况比电阻值,并对计算值和实测值进行对比。结果表明,低低温工况时飞灰工况比电阻值明显低于常温工况,但模型计算值与实测数据尚存一定差距,该模型仍需修正。

| Abstract: | To study the resistivity characteristics of fly ash under low-low temperature in ESP and discuss the feasibility of using mathematical model to calculate the resistivity of fly ash,the resistivity of fly ash in Yuhuan,Wenzhou and Chengxing power plants was measured online by BDL fly ash resistivity tester and calculated by R.E.Bickelhaupt model.Then,the calculated and measured values were compared.Results show that the resistivity under low-low temperature is significantly lower than that under normal temperature.However,there is a certain gap between the calculated and measured values,so the mathematical model needs further correction. |
