不同锅炉补给水水源的技术经济比较

Technical and economic comparison between two processes respectively using different water sources as boiler makeup water

针对直接使用地表水与利用循环冷却水系统的排水作为火力发电厂锅炉补给水进行技术经济比较,为电厂合理选择适合的锅炉补给水处理水源作参考。研究结果表明,项目采用地表水做水源的方案电耗低、基建费用低、制水成本低、自动化程度高、运行及管理方便、检修维护工作量小,但水耗指标略差。从经济、技术、环保等方面进行综合考虑,推荐采用地表水作为锅炉补给水水源。

The technical and economic comparison between the two processes respectively using surface water and drainage from circulating cooling water system as boiler makeup water was carried out, which provided a reference for power plants selecting source of makeup water for their boilers. The results of the study showed that, using surface water as boiler makeup water had advantages of low power consumption, low capital construction cost, low water producing cost; high degree of automation, convenient for operation and management, small repair and maintenance workload, however, its water consumption was relatively large. Based on the comprehensive consideration from aspects of economy, technology, environmental protection and so on, surface water was finally recommened as a proper source of boiler makeup water.
