简析电站锅炉补给水一级除盐方法

Brief Analysis of Primary Desalting of Make-up Water in Power Station Boiler

电站锅炉补给水除盐是保证机组安全、稳定、连续、高效运行的重要手段之一。以电站锅炉补给水一级除盐技术为研究对象,分析了离子交换法、反渗透法、电渗析法的发展历史、工作原理、优缺点等,并对比其经济性,探讨其适宜的原水含盐浓度。对新建电站锅炉补给水一级除盐方法的选择提出了建议。

Desalination of power station boiler make-up water is an important method to ensure the system＇s safe, stable, continuous and efficient operation. Taking the primary desalination technology as an example, analyzes the histories, principles, merits and demerits of Ion exchange, RO method and electro-dialysis, and then discusses the suitable salt concentration of raw water considering the economic characteristics of the three method. In conclusion, puts forward suggestions for selection of primary desalting technology for newly built power station boiler.
