Extern gefeuerter Gasturbinenprozess: Potenziale und Entwicklungsstand (Teil2)

The externally fired combined cycle (EFCC) process utilises a high temperature heat exchanger to transfer the heat of a dirty flue gas to a clean working medium. In comparison to other combined cycle concepts, like integrated gasification combined cycle or pressurized pulverized coal combustion, the problems of hot gas cleaning are avoided. The first part of the publication (BWK 5/02) deals with the possible concepts and the efficiency potential of the externally fired combined cycle. The applicability of metallic and ceramic heat exchanger materials are discussed. The second part summarizes the state of the art and presents the basic design of a ceramic heat exchanger.     «
