摘要
为降低机组厂用电率,部分燃煤电厂引风机采用汽轮机驱动,使汽轮机冷端优化复杂化。针对国内某1 000 MW燃煤机组引风机汽轮机真空偏低的问题,结合主机冷端优化,考虑电厂实际运行中的可操作性,提出切实可行的提高方法及最佳运行方案。
To reduce power consumption rate, the induced draft fan in some coal-fired power plants is driven by steam turbine, which makes the cold end optimization become more complex. To solve the low- vacuum problem occurring in the steam turbine driving induced draft fan of a 1 000 MW coal-fired unit, an applicable operation scheme was proposed, considering cold end optimization of the unit and actual operability of the scheme.
