火力发电厂风机变频节能分析和运行措施

Analysis on energy-saving effect of variable frequency technology for draught fans of thermal power plants and operational measures

对华电四川发电有限公司攀枝花分公司2台150 MW循环流化床机组锅炉风机实施了变频技术改造,通过对风机设备改造前、后能耗指标对比分析,提出了节能改造技术措施,有效降低厂用电率,提高了经济效益。

Using the variable frequency technology,the driving systems of the draught fans of two 150MW CFB boilers in Panzhihua Branch of Huadian Sichuan Power Generation Corporation Limited were reformed.Based on comparative analysis on the energy consumption indexes of the fans before and after the reformation,the technical measures of energy-saving reformation were put forward.So the service power consumption rate was reduced effectively,and the economic benefit was improved.
