通过对600 MW超临界燃煤机组的引风机电机变频改造、一次风机轴流改造进行分析,实践证明,风机改造降低厂用电率,减少起动电流、有利于锅炉安全、经济运行,达到了节电降耗的目的。
Through the transformation of the induced draft fan motor in 600 MW supercritical coal-fired units and the primary fan axial flow retrofit analysis, the practice proved that the fan transformation reduced the plant power consumption rate and reduced the starting current, which was in favor of the safe and economical operation of the boiler and reached the section Power consumption of the purpose.
