Analysis of trace anions in the water-steam cycle in power plants

Abstract

This study offers some insight into the significance of water quality control in thermal power plants. In order to maintain high reliability indices in thermal plants and to realize the expected lifetime of these plants, high water quality should be accomplished. Also, the working tools of the analyst in thermal power plants and the types of problems, which help in solving daily tasks, are discussed. The difficulties the analyst might face are indicated. This review considers the implementation of standard control and diagnostic parameters crucial for water quality in all segments of a water-steam system. The subject of this paper was to analyze anion traces in the water-steam cycle, using a modern, highly sensitive instrumental method the method of ion chromatography (1S). Thus, the possibility of monitoring ionic species that can cause corrosion processes in the water-steam system is examined.
