Drop Technique

The electrical potential drop technique is one of the promising methods for monitoring the pipe wall thinning. In order to verify this method, preliminary thickness measurements were conducted for uniform and local thinning created on plate specimens. The result showed the electrical potential drop technique had a good performance equal to the ultrasonic testing method. The success in the preliminary tests allowed this technique to be applied to some pipes in thermal power plants in order to monitor the wall thinning and this on-line monitoring has continued for two to three years. It was confirmed that this technique was valid in terms of a long-term durability. Following these results, technical requirements on the potential drop technique were proposed to the JSME (the Japan Society of Mechanical Engineers) Rules on Pipe Wall Thinning Management for Thermal Power Generation Facilities (JSME S TB1-2006) and stipulated in those rules. In this paper, these rules are simply introduced and the on-line monitoring of the pipe wall thinning by means of the electrical potential drop technique is discussed through the results in the plate-specimen-tests and the real-pipe-tests in operating thermal power plants.

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.

In order to maintain high reliability indices in thermal power plants and to realize the expected lifetime of these plants, high water quality should be accomplished. Also, an insight in the working tools of the analyst in thermal power plants and into the types of problems, which help in solving daily tasks, is given. This review considers the implementation of standard control parameters crucial for the indication of water quality in all segments of a water-steam system. A concept of modernization of the system for analytical control and monitoring in the water-steam cycle is suggested.
