本文从能量利用角度,对热水、汽水混合物的全流发电方法和闪蒸发电方法进行了比较。在汽水混合发电系统中,提出当量热水温度概念,简化了汽水混合发电系统的热力计算。在实际汽水发电系统中,对与闪蒸发电量相同的全流发电系统进行热力计算,得到了不同热源温度、干度下全流动力机的最小内效率曲线。 In this paper, the full-flow power generation method and the flash-power generation method of hot water, steam and water mixture are compared from the perspective of energy utilization. In the steam-water hybrid power generation system, the concept of equivalent hot water temperature is proposed, which simplifies the thermal calculation of the steam-water hybrid power generation system. In the actual steam-water power generation system, the full-flow power generation system with the same amount of flash-generated power is subjected to thermal calculation, and the minimum internal efficiency curve of the full-flow power machine with different heat source temperature and dryness is obtained.
