摘要
发电厂采用冷却水塔除雾技术,可以达到环保、节约水耗的目的。介绍了将采用冷却水塔除雾技术应用于大型燃气联合循环机组时,在系统使用时存在隐患。以奉贤热电厂通过优化PLC逻辑、改进设备稳定性、增设自动保护等内容为例,阐述了提高除雾系统安全性、稳定性的技术措施。
Cooling tower defogging technology adopted in power plant can achieve the purpose of environmental protection and water consumption saving. This paper introduces the hidden danger in the application of cooling tower defogging technology to large gas combined cycle unit. Based on the introduction of PLC logic optimization,equipment stability improvement and automatic protection in Fengxian Thermal Power Plant,this paper describes the technical measures to improve the safety and stability of the defogging system.
