Design evaluation of a small high-temperature reactor for process heat applications

The high-temperature reactor is also suitable for process heat application, in particular in smaller size units. On the basis of the results of R and D and demonstration work on coal refinement some improvements for small high-temperature reactors of process heat applications are discussed. These are: Increase of the gas outlet temperature, the gas inlet temperature, the decrease of the overall system pressure, and non-integration of the primary circuit components. Some of these design evaluations are based on the results of the pre-project for the extension of the AVR-reactor in Juelich to be used as a process heat plant. (orig.)
