Heat exchanger installation for a closed gas circulatory system, such as a thermal power plant, for example

摘要

A closed helium gas circulatory system includes a compressor, nuclear reactor, turbine, and heat exchanger installation serving as recuperator and precooler, the recuperative heat exchanger and the precooling heat exchanger of the installation both having tubes, the tubes of one of the heat exchangers being disposed concentrically or coaxially to those of the other heat exchanger.
