Description
The process heat required for nuclear coal gasification is provided by helium circuits at 900 to 9500C and 40 to 50 bar. Whereas in the primary (nuclear) heat transfer system use is made of ceramic gas ducts of graphite or CFC (carbon fire-reinforced carbon), metallic gas ducts have found acceptance in the subsequent secondary systems. The high temperatures and pressure of the hot gas require either coaxial gas ducts and/or reliable internal insulation. Pressure and temperature loads must be strictly kept apart from each other. The requirements and constraints, the approaches adopted and their experimental confirmation are discussed in this article. (orig.)
Abstract (German)
Fuer nukleare Kohlevergasung benoetigte Prozesswaerme wird durch Heliumkreislaeufe bei 900 bis 9500C und 40 bis 50 bar zur Verfuegung gestellt. Waehrend im primaeren (nuklearen) Waermeuebertragungssystem keramische Gasfuehrungen aus Graphit oder CFC (kohlefaserverstaerkter Kohlenstoff) eingesetzt werden, hat sich in anschliessenden sekundaeren Systemen die metallische Gasfuehrung durchgesetzt. Die hohen Temperaturen und Druecke des Heissgases erfordern entweder koaxiale Gasfuehrungen und/oder zuverlaessige Innenisolierungen. Druck- und Temperaturbeanspruchungen sind strikt voneinander zu trennen. Die Anforderungen und Randbedingungen, die eingeschlagenen Loesungswege und deren experimentelle Absicherung sind im vorliegenden Beitrag dargestellt. (orig.)Additional details
