摘要
本文回顾和总结了望亭电厂第一台国产300MW机组的化学水处理及监督工作,文章强调了慎重选择补给水源和预处理的重要性,并指出补给水处理设备应能满足水源水质变化的要求,否则要有应急措施;应提高凝结水精处理的质量,以确保给水水质;给水联合处理将为减轻水汽系统和锅内腐蚀、结垢开创新的途径:认真执行有效的机、炉停用保护措施:防止凝汽器和热交换器管泄漏以及逐步实现化学监督现代化管理是大机组防腐防垢的重要内容。
The water treatment and chemical surveilance of first domestic 300MWunit in Wanting Power Plant is reviewed and summarized in this paper. Careful selectionof make up source and the importance of pretreatment are emphaszed by theauthor.The make-up water treatment eqipment shoud satisfy the wide fluctuation of rawwater quality, or emergency measures be provided. Condensate polishing shoud beimproved to assure feedwater quality.Combined Feedwater Treatment(CWT).aduptedrecently by the plant, has been proved to be a successful new approach to minimize thecorrosion in steam-water cycle and the boiler. Prevention of condenser tube leak,corrosion prevention of lay-up power eqipments and modernization of water qualitymanagement still are,and will be, important premises for corrosion prevention of largeunit.
