Flingern's corrosion diagram

Flingernic corrosion diagram with extensions

The Flingernian corrosion diagram shows areas of high temperature corrosion as a function of the flue gas velocity and (tube) wall temperature. It has been empirically developed for the conditions in the steam generator of waste incineration plants (MVA).

The diagram is used for the assessment of steels installed in the flue gas flow of a boiler, with regard to corrosion resistance. It is assumed that the higher the flue gas temperature and the wall temperature of the material to be assessed, the poorer the corrosion resistance.

The first investigations were carried out from 1978 to 1980 at the MVA Düsseldorf-Flingern, from which the name of the diagram is derived. In the meantime, the diagram has been expanded several times and the flue gas speed has been added as an additional criterion. Since the topic of high-temperature corrosion is also important in biomass heating plants, the Flingern corrosion diagram is also becoming more and more important here. Single-level Edit source text
