加热器是汽轮机回热系统重要设备之一,其给水加热性能可用上端差(又称出口端差)和下端差(又称入口端差)来表示。上端差是指加热器进汽压力对应的饱和温度和给水出口温度之差;下端差是指离开加热器壳侧的疏水出口温度和进入管侧的给水进口温度之差。考虑到加热器上端差对机组经
Heater is one of the important equipment of steam turbine heat recovery system. The performance of feed water heating can be expressed as the upper difference (also known as outlet differential) and the lower differential (also called inlet differential). Difference between the upper end refers to the heater inlet pressure corresponding to the saturation temperature and the outlet temperature difference; lower end of the difference is leaving the heater shell side of the hydrophobic outlet temperature and into the tube side of the inlet temperature difference between the water. Taking into account the difference between the upper heater on the crew
