汽动引风机在超超临界1000MW机组中的应用
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。
Abstract
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.
