【摘要】 介绍江西丰城电厂3号机组应用发电机内冷水微碱性循环处理技术的经验和技术原理。江西丰城电厂为了减缓发电机铜线棒的腐蚀,改变传统的采用添加铜缓蚀剂、频繁换水作为发电机内冷却水的调节方式,采用发电机内冷水微碱性循环处理技术。内冷却水通过微碱性处理后含有微量的氢氧化钠,有效地减缓了发电机线棒的腐蚀。更多还原

【Abstract】 In order to alleviate the erosion of large generator’s copper bar,the means of adding copper inhibitor,changing water frequently are introduced by Jiangxi Fengcheng Electric Plant.However,but the quality of water is poor,and it cannot meet the standard of DL/T801-2002“Requirements of water quality and internal cooling water system for large generator".In this paper,the application experience the principle of recycling technology with weak alkaline water for internal cooling system in the No.3 unit of FCEP is primary introduced.The internal cooling water after treatment contains very little NaOH,and its quality is much better than the standard in DL/T801-2002,Under these water quality conditions,copper is in the state of self-passivity.Thus,the copper bar is protected well.更多还原
