摘要：
The paper is concerned with the thermodynamic analysis of a multi-stream heat exchanger system for the Allam cycle and the development of a regenerator heat flow chart. The multi-stream heat exchanger thermodynamic analysis and development procedure are described in detail. The regenerator system constructed of five double-flow heat exchangers has 2.5% lower heat power than the ideal heat exchanging system. Besides, a subsequent flow interaction principle for the transfer of a maximal heat amount is proposed: it is necessary to begin with the cooling of the heating flows with minimal temperatures.
