摘要
针对某电厂超超临界1 000 MW机组锅炉引风机与脱硫增压风机合并后采用小汽轮机驱动引风机,分析汽动引风机对电厂主要运行指标的影响。分析结果表明,大容量风机采用小汽轮机驱动后,避免了风机起动过程中对厂用电系统的冲击,显著降低了厂用电率。
After merging the induced draft fan（IDF） of boiler with the booster air fan used for flue gas desulphurization of ultra-supercritical 1000 MW unit in one power plant,a small-turbine driven IDF has been adopted.The influence of turbine-driven IDF upon main operating indices of power plant has been analysed,results of analysis show that the adoptation of turbine driven large-capacity IDF can avoid impulse to the auxiliry electric system in start-up process of IDF,reducing substantially the consumption rate of service power.
