Corrosion protection in power plants and heat recovery systems against acid attacks in the high temperature range
CeraNovis offers coating systems with long-term stability that are used as temperature-resistant corrosion protection coatings against acid attack. The solvent-based systems, known as Nanocomp ECO, are applied by spraying or dipping and cure at room temperature. Nanocomp ECO50 has very good non-stick properties and provides protection against attacks from sulphuric and nitric acid. This coating is temperature-stable up to 300°C.
Nanocomp ECO70 is a protective lacquer that is stable up to temperatures of 600°C and is also highly resistant to thermal shock. The resistances created with the coating cover all common acids that can occur in flue gas when the temperature falls below the dew point. After exposure to high temperatures, even aqua regia vapors do not lead to corrosion on a steel surface coated in this way and damaged by a cross-cut.
The coatings are specifically used in heat exchangers because their protective function does not require high coating thicknesses. Effective protection is provided at approx. 50µm. The impairment of heat transfer is negligible and in any case less than that of rusted surfaces.
The coatings are designed for industrial use in waste incineration plants in economizers and tube bundle heat exchangers as well as on other surfaces at risk of corrosion.
The range also includes pure non-stick coatings to maintain the function of fan wheels and dust silos.
