摘　　要：某热电厂为节能降耗,降低厂用电,在大修期间,将原设计的2台引风机改为动叶可调式轴流引风机。对改造后的风机进行性能试验,测量并计算三种不同负荷下风机性能数据。结果表明,改造后的动叶可调轴流风机能适应不同负荷工况,基本达到设计参数。由于煤质变化和锅炉烟气量变化,引风机效率与设计之有一定偏差,但可满足运行要求。In order to save energy and reduce auxiliary power, during the overhaul, a thermal power plant changed the original two induced fan design to variable pitch axial -flow induced draft fan. After transformation, measuring and calculating the fan performance data at three different loads. The results show that after the transformation of the adjustable rotor blade axial fan can adapt to different load conditions, basically meet the design parameters. Due to changes in coal quality and boiler flue gas volume, Fan efficiency and design values have a certain bias, but can meet the oper- ational requirements.
