本文介绍了自热回热式热力过程的分析和计算方法。自热回热技术是近年来发展起来的一种技术，其特点是总的工艺热量可以在工艺过程中再循环，从而显著降低能耗。虽然这种技术可以在工艺中实现完美的热循环，但热过程所需的最小能量以前没有描述过。根据本文的理论和图解分析，从火用的观点来看，自热回热过程可以达到接近传热所需能量的能量需求。此外，推导出了最小传热能量的简单计算方法，并以此作为热回收技术的目标值。因此，该技术支持过程强化，并有希望为工业界在设计热过程时检查节能潜力。
In this paper, an exergy analysis and a calculation method for a self-heat recuperative thermal process are described. Self-heat recuperation technology has recently been developed and has the characteristics whereby total process heat can be recirculated within the process, leading to a marked reduction in energy consumption. Although this technology can achieve perfect heat circulation in the process, the minimum energy required for the thermal process has not previously been described. According to both the theoretical and graphical analyses in this paper, self-heat recuperative thermal processes can achieve energy requirements close to the energy required for heat transfer from an exergy point of view. In addition, the simple calculation method for the minimum energy required for heat transfer was derived to be fixed as a target value of heat recovery technology. Thus, this technology supports process intensification and is promising for industry to examine the energy saving potential when designing a thermal process.
