【摘要】 文中针对某火电厂化学水系统扩容改造所采用的超滤反渗透预脱盐装置对原水温度的要求,根据循环水经凝汽器的换热后出水提高10℃左右的特点,将化学水原水取水口从循环水进水口改至循环水出水口,利用机组凝汽器出水作为化学水制水的原水,以此减少用于原水加热的蒸汽,达到节能的目的。更多还原

【Abstract】 The ultrafiltration reverse osmosis desalting device is used for expanding and upgrading the chemical water treatment system in the power generation.It has the needs on water temperature.According to the feature that the circulating water outlet temperature will be increased by 10℃ or so after heat exchange from condenser,the intave of chemical raw water is changed from circulating water inlet to outlet.It reduces the steam for heating the water and saves energy.更多还原
