Successful management of the ferrous chloride dosing system and the Taprogge ball condenser tube cleaning system at Eraring power station (EPS), NSW, Australia, relies on measurements of copper in the salt cooling water prior to and after each condenser pass. However, obtaining an accurate copper measurement in the challenging matrix of salt water used has proven difficult. EPS conducted trials of two methods for the measurement of copper in natural waters, differential pulse anodic stripping voltammetry (DPASV) and graphite furnace (electrothermal) atomic absorption spectroscopy (GFAAS). This paper discusses the results of copper measurements from the various trials undertaken on the condenser systems. Based on the trials of this instrument, DPASV was chosen as the preferred method of analysis for the purposes of optimising condenser performance and efficiency, minimising ferrous chloride chemical dosing and tube corrosion, and maximising heat transfer.
