1. The temperature rise of circulating water is the difference between the cooling water outlet temperature and the inlet water temperature of the condenser.
2. The circulating water temperature- rise is explained as an important indicator of economic operation of condenser. Under a certain steam flow, there is a certain temperature rise value.  The temperature-rise can be monitored for analyzing whether the cooling water of condenser meets the requirement of turbine exhaust cooling or not. In addition, the temperature- rise can also be used for analyzing whether the copper tube of condenser is clogged and cleaned etc.
