ELECTRIC RESISTIVITY MEASURING DEVICE, COAL COMBUSTION PLANT WITH THE SAME, AND ELECTRIC RESISTIVITY MEASURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an electric resistivity measuring device capable of simulating dust in exhaust gas within an electric dust collector, a coal combustion plant with the same, and an electric resistivity measuring method thereof.

SOLUTION: The electric resistivity measuring device includes a collection part 40 having a discharge electrode 41 which discharges to exhaust gas extracted from a duct at upstream side of the electric dust collector and a collection electrode 42 which collects charged dust in the exhaust gas by discharging from the discharge electrode 41; and a measuring part 50 which communicates with the collection part 40, has a cell on which the dust collected by the collection electrode 42 is accumulated, and can measure a current flowing through the dust by applying a voltage to the dust accumulated on the cell.
