600 MW燃煤机组汽动引风机节能减排评估

摘要

针对大型燃煤机组改造项目，将给水泵汽轮机驱动引风机的方式应用于600 MW燃煤机组，对其节能减排效果进行评估和分析。计算和分析结果表明：相比于电动机驱动方式，给水泵汽轮机驱动方式具有减少厂用电量、降低供电煤耗、提高发电厂收益、减少污染物排放等优点，其中在亚临界压力机组上应用的节能减排效果最佳。%In the large coal-fired units transformation,the driving mode of induced draft fan of feed pump steam turbine is applied to 600 MW coal-fired units.The effect of energy-saving and emission reduction is evaluated.The calculation and anal-ysis results show that the driving mode,compared to electric driving mode,can reduce auxiliary power consumption,coal consumption for power supply,improve benefit of power plant and reduce pollutant emissions.The application of this mode in subcritical units is more significant in energy-saving and emission reduction.
