ELECTRICAL RESISTANCE MEASURING DEVICE, COAL FIRED POWER PLANT COMPRISING SAME, AND ELECTRICAL RESISTANCE MEASURING METHOD THEREOF

摘要

Disclosed are an electrical resistance measuring device that is capable of simulating dust in exhaust fumes inside an electric dust collector, a coal fired power plant comprising same, and an electrical resistance measuring method thereof. The electrical resistance measuring device comprises a collection unit (40) comprising an electrical discharge pole (41) that discharges electricity toward exhaust fumes that are extracted from a smoke duct that is upstream of the electric dust collector and a collection pole (42) that collects the dust within the exhaust fumes that has been charged by the electrical discharge from the electrical discharge pole (41); and a measuring unit (50) that communicates with the collection unit (40) and comprises a cell that accumulates the dust that is collected by the collection pole (42), such that the measuring unit (50) is capable of measuring the current flowing through the dust that is accumulated in the cell by impressing a voltage upon the dust.
