Research on the Reasons for Excessive Conductivity of Water,Steam,and Hydrogen in Thermal Systems
After the maintenance of the IGCC unit,it was started and connected to the grid,and the online hydrogen conductivity meter was put into operation.The phenomenon of water vapor hydrogen conductivity exceeding the standard was found.Through the inspection and analysis of the water vapor quality of the unit's thermal system,it was preliminarily determined that the cause of the problem was the dissolution of impurities such as fluoride ions in the high-temperature water vapor in the newly replaced steam sampling rack pipes,valves,heat exchangers,and other parts,resulting in high steam hydrogen conductivity.However,the actual water vapor quality is still good.
