From an economic point of view Underground Coal Gasification (UCG) is a promising technology that can be used to reach coal resources that are difficult or expensive to by conventional mining methods. Furthermore, the process addresses safety concerns, by avoiding the presence of workers underground. An optimal UCG process requires the integration ...

Bei der Verbrennung oder Vergasung von Kohlen in Kraftwerken werden alkalimetallhaltige Stoffe (Alkalien) freigesetzt, die zur Korrosion heissgasbeaufschlagter Anlagenteile fuehren koennen. Die hohen Prozesstemperaturen besonders effiziente Kombikraftwerksverfahren erhoehen das Schadenspotential der Alkalien und machen Vorkehrungen zur Reduzierung ...
Coal contains most elements of the Periodic Table in trace quantities. During gasification and combustion, many trace elements are released from the fuel in vapour form and/or in association with particulates released by the process. In addition to causing corrosion damage to process plant, many of these trace elements (e.g As, Hg, etc.) constitute...
