Present and Future Mineralogical Problems of Power-Station Technology

摘要

A number of power station engineering problems to whose solution mineralogy can make a contribution are discussed. The problems relate among other things to organic impurities in fuels and their thermal-conversion products (slag, ash, fly ash). Gas-side corrosion, slagging, fouling, and some aspects of air pollution by fine dust are discussed. Problems of high temperature oxidation of steel by water and steam and precipitation from high-pressure steam, for instance in turbines are mentioned. Examples chosen to illustrate the application of mineralogy to nuclear-energy generation are special fuel elements and petrographic aspects of final storage. Finally, geochemical and petrological problems of geothermal energy are examined although the latter probably has little relevance to the Federal Republic of Germany. (ERA citation 08:025985)
