Comparative studies of the corrosion and long-term stability of vitrified e-filter dust from waste incinerators, granules from high-temperature waste incineration plants and a model glass

摘要

The objective of this study was to describe the corrosion behaviour of vitrified residues of municipal waste incinerators by using standardized short-term and long-term leaching and corrosion test methods. The results for the vitrified product were compared to the results for granules from high-temperature waste incineration plants and a model glass. The test methods used in this work are, on the one hand, a German and a Swiss test [1 and 2] to describe the possibility for the disposal of waste and, on the other hand, test methods [3 and 4] to characterize the corrosion behaviour of glass products. The results according to the different methods and their changing test parameters like temperature, corrosion time and leaching solution are presented.
