Investigating the Mineralogical Composition of Flying Ash Pulps from the Aspect of Waste Quality

Nowadays coal-based power plants have still a 25% share in energy production in Hungary. Consequently, professional treatment of the yearly accumulating large volumes of ash/flying ash is an important task from environmental, as well as national economic aspects. Since power plants have gradually switched during the recent years to hybrid-fluid technology, substantial part of sulphur accumulates in fine ash/flying ash. It is important to know in which form the sulphur component becomes absorbed in the flying ash-water pulp of approximately 1:1 mixing ratio. This study presents the thematic as well as temporal evolution of the detailed determination of mineralogical composition

CORROSION AND ELECTROCHEMICAL RESEARCHES

We wish to introduce the work of the research group for corrosion and electrochemistry of Institute of Inorganic Chemistry, Technical University of Budapest. The main fields of our investigations were the electrogalvanizing of palladium-nickel alloy-coatings, the study of the sealing of the anodic oxide-layers, the corrosion-resistance of titanium-carbide steel- alloys, the effectiveness of inhibitors protecting the steel reinforcement of cellular concrete and the study of the corrosion effect of chemical agents used for salting winter roads
