引风机节能改造及性能试验研究

Energy-saving reformation of induced draft fan and testing study of its performance

华电青岛发电有限公司#1、#2炉投产后一直存在引风机运行效率偏低、能耗较高等问题。2008年小修期间委托西安热工研究院有限公司对#2炉引风机进行了改造。改造后试验表明,引风机效率提高了15%～20%,节能效果十分显著。

After 1 and 2 boilers of Huadian Qingdao Power Generation Corporation Limited putting into operation,the efficiency of induced draft fan was lower,and its energy consumption was higher all the while.In minor overhaul period at 2008,the 2 induced draft fan had been reformed by authorized Xian Thermal Power Research Institute.The test after reformation indicated that the efficiency of induced draft fan had been increased by 15%～20%,the energy-saving effect was very obvious.
