In the last few years, a concentrated research effort has led to a better understanding of the corrosion problems in flue gas desulfurization (FGD) systems of coal fired power plants. At first look, operation of a typical limestone FGD system appears very simple, hence the first generation scrubbers of early to mid 70's were designers inspiration. However, the designers inspiration soon turned into a utility's nightmare due to failures of metals and non-metals, both failing in a an embarrassingly short time. A solution was needed which had to be reliable, simple, and cost effective. This objective was met via the application of wallpaper concept, which now has been very well accepted in the industry and is becoming increasingly more popular due to the many successful case histories. This paper describes the wallpaper concept solution, the fabrication techniques, the experiences at certain utilities, the precautions which need to be followed, the associated economics, and some case histories.
