Experiences concerning the service life of rubber linings applied in flue gas desulfurization plants
- Kerarnchemie GmbH, Siershahn (Germany)
Since the beginning of the eighties scrubbers and other components in European FGD plants have been protected against corrosion using rubber lining. Extensive experience is available based on service lives of rubber lining of more than 15 years. The paper will consider the various rubber types and curing systems used. While the USA and Japan had already begun retrofitting their existing coal-fired power stations with flue gas desulfurization (FGD) plants in the seventies, Germany followed suit in the eighties as a result of the decree issued for large-scale firing plants. Concurrent with this development retrofitting has also been enhanced in other European countries like Austria and the Netherlands, later followed by Denmark, Finland and England. After the collapse of the Eastern Bloc retrofitting work has been implemented in Eastern Germany, Poland, the Czech Republic and Slovakia. Today FGD plants are being put into operation in Spain, Italy, Turkey and Greece or are on the verge of being put into service. More than 150 plants of this kind are operated by using the wet-scrubbing process with limestone or calcium hydroxide suspensions.
