電廠化水系統作為重要的輔助車間和輔助系統，特別是大型火電廠、供熱電廠的化水處理車間，處理量大，工藝復雜，工藝要求高，其運營的好壞直接關系到電廠的安全運作及可靠性。
國外大部分電廠采用反滲透裝置+離子交換裝置的組合工藝，它與單純的離子交換系統相比再生樹脂的酸、堿用量可節約50%-90%，且制水流程靈活，對原水濃度波動適用性強，出水水質穩定，即保證了生產，又減少了工人的勞動程度，獲得了明顯的經濟效益、環境效益和社會效益。
我國從20世紀70年代末開始有電廠引進國外用反滲透技術制備高壓鍋爐補給水的技術，積累了較為成熟的經驗，取得了很大的經濟效益。
As an important
accessory plant and system, especially the water
treatment shop of large thermal power station
and power plant, the water system has large
treating capacity ,complex process and high
process requirement ,the running of the system
relates to the safe operating and dependability
of the electricity plant.
most of the electricity plants adopt the group
tech of reverse osmosis equipment and ion
exchanger,it can save 50%-90% of acid and alkali
consumption of regenerated resin compared with
single ion exchanging system, and due to its
flexible water-making process ,strong
adaptability to the fluctuation of concentration
of raw water ,and stable quality of water
output, the production is guaranteed ,and the
labor intensity is reduced ,the economic
,environmental and social benefits are gained.
In China ,the reverse osmosis tech was
introduced to prepare supply water for the
high-pressured boilers in the 70s of the 20th
century ,so we are experienced in this field and
gain high benefit.
