摘要/Abstract

摘要： 利用化学在线清洗技术，采用Y-CH107清洗剂和辅助生物黏泥剥离、清洗及钝化一体化在线清洗工艺，在不影响机组发电的情况下，pH值控制在4～5，实施了3×390MW机组循环冷却水系统的同步在线清洗，有效控制系统内不同材质的腐蚀速率并取得了满意的效果。以杭州华电半山发电有限公司3×390MW燃气-蒸汽联合循环汽轮发电机组为例，简述了循环水系统化学在线清洗的技术运用情况及其实施过程和清洗效果，对产生的经济效益进行了分析。

Abstract: The synchronized online chamecial cleaning of 3×390MW units circulating water system was implemented by using the chamecal online cleaning technology, in which the Y-CH107 cleaning agent was used, the integrated biofouling removal, cleaning and passivation processes were adopted. The cleaning process did not influence units generation, the pH value was controled in range 4 to 5. Then the corrosion rates of materials in the system were controled effectively. Taking the 3×390MW combined gas and steam turbine units of Hangzhou Huadian Banshan Generation Corporation Limited as examples, the application, implement process and effect of circulating water system chamecal online cleaning technology were described briefly, and its economic benefit was analyzed.

Key words: synchronized on-line chemical cleaning, gas turbine generator set, circulating cooling water system, condenser fouling, cleaning plan, cleaning effect, economic benefit analysis
