Resistivity characteristics of fly ash under low-low temperature

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.
