Abstract

Hydrogen conductivity an important index characterizing the water vapor purity in power plant and its erosion. This article puts forward an intelligent measurement method for hydrogen conductivity

in which the electric regeneration device is employed to replace the conventional ion exchange resin column. This method solves many problems occurred in hydrogen conductivity measurement for power plants and truly realizes continuous online measurement of hydrogen conductivity. This intelligent hydrogen conductivity measurement method was applied to two power plants

and it turns out that the results are accurate and reliable

this method can rapidly reflect the change in water vapor quality

comparing with the conventional method. Moreover

this method shortens the washing time of the instruments when the unit starts frequently

and greatly reduces the sampling water quantity. This method promotes the chemical supervision technology

and is of great significance to control the corrosion of equipments in power plant.
