Investigations on Corrosion Protective Layers in Waste Incineration Plants

Peter Crimmann, Dietmar Bendix, Martin Faulstich, Sulzbach-Rosenberg / D WTERT-Germany 2005

Corrosion in the hot gas area of waste incineration plants is a severe problem that often causes premature damage of components. In general, these components are made of base materials, which are not stable in corrosive conditions (boiler steel). Thermal spraying is an alternative to the most usual process cladding, which has the potential to create cost-efficient protective coatings. Until now, there are still not enough experiences about quality assurance (porosity, oxides) and long run behaviour inside the incineration plants with sprayed coatings. Since many years, ATZ Entwicklungszentrum is involved in the development and/or advancement of materials, technologies, and applications of thermal spraying for corrosion protection. Currently, pipes, coated with different materials and different technologies are tested by different strategies (corrosion tests under laboratory scale and/or directly in incineration plants).

Management of Solid Wastes in Vietnam

In the past decade, strong economic growth and uncontrolled urbanization have greatly magnified the problems with Vietnam’s solid waste management system, pushing waste management to the forefront of environmental challenges with which it must contend. Not only has there been an increase in the amounts of waste generated, the composition of the waste has changed as well. The current system is already overtaxed due to lack of institutional capacity and insufficient human and capital resources as can be evidenced by low collection rates and inadequate waste facilities. Given socio-economic trends, the issue of how to deal with its solid waste will only become more critical as Vietnam industrializes.
