Forschungs- und Entwicklungsarbeiten zur Wasserdampf-Vergasung von Kohle, Projekt Prototypanlage Nukleare Prozeöwärrae - Statusbericht zum Ende der Konzeptphase vom 01.08.1975-30.11.1976

摘要

The development of a coal gasification process using a high temperature nuclear reactor to meet the energy requirements of the process is described. A key point in the development is the gas generator in which the nuclear heat is transferred into a fluidized bed of coal and steam via an intermediate loop and a heat exchanger immersed in the bed. On the basis of former results concerning reaction kinetics and heat transfer, further experiments with different devices were performed and the program for the testing and the development of new alloys to be used was continued. A pilot plant (0.2 T/hr) using an electrically heated helium loop was constructed and is now in operation. The data gathered confirm the feasibility of the gas generator as well as the process and are being used for the design of bigger plants.
