摘要
介绍了某电厂660MW超临界机组将静叶调节汽动引风机改造为双级动叶调节汽动引风机,解决了静叶调节汽动引风机共振、低负荷易失速、并入引风机困难等问题,同时提高了风机性能,降低了汽动引风机的小汽轮机耗汽量。
The static lobe-regulated steam induced draft fan was retrofitted into a two-stage dynamic lobe-regulated steam induced draft fan in a 660MW supercritical power plant,which solved the problems of resonance of the static lobe-regulated steam induced draft fan,easy to stall at low loads,and difficult to merge into the induced draft fan,and at the same time,it improved the performance of the fan,and lowered the steam consumption of the steam induced draft fan for the small steam turbine.
