ABSTRACT:
The heat exchanger system is used for gas-cooled high-temperature reactors. The high-temperature primary gas passes over a nest of blind tubes and thereafter flows over the tubes of a plurality of counter-current heat-exchangers disposed about a jacket encasing the blind tubes. The cool working gas flows into the system via a header and then passes through the tubes of the counter-current heat-exchangers before passing into the blind tubes. The working gas is exhausted via insert tubes within the blind tubes. The maximum temperatures on the heat exchanger surfaces occur at the closed ends of the blind tubes. However, these parts are substantially stress free in normal operation.
The heat exchanger system may be constructed to permit ready disassembly of the insert tubes for inspection and replacement purposes.
