SUITABILITY TESTS FOR RUBBER LININGS USED IN FGD COMPONENTS AND EVALUATION OF SERVICE LIFE

摘要

Rubber linings are applied as a corrosion protection system for the interior surfaces of C- steel in flue gas desulphurization plants (FGD). Given that over twenty years of operational experience has now been accumulated in the utilization of this material in corrosion protection systems, staff members of the power station operators, of the rubber lining industry as well as independent test institutions in Germany have jointly worked out an instruction sheet in which 1. Test procedures determine the usability of soft rubber linings in flue gas desulphurization plants as well as 2. Testing criteria and standard values for the assessment of the service life of soft rubber linings in flue gas desulphurization plants have been formulated. The objective of this lecture is to introduce and explain the contents of this new instruction sheet.
