| 摘 要： | 文中以某电厂1000MW超超临界机组的设计和运行参数为基础,论证了三合一风机采用汽轮机驱动的可行性;并与采用电机驱动方案进行技术经济比较,推荐经济效益更优的凝汽式小汽轮机驱动引风机方案。分析结果表明:大容量引风机采用小汽轮机驱动后,避免了电动引风机造成的启动电流过大,厂用电电压等级需要提高等问题,显著降低了厂用电率。

| Abstract: | Based on the design and operation parameters of the ultra-superitical 1000MW unit, the fesibility of steam turbine-driving induced fan has been analyzed in this article by comparing the economic efficiency of motor-driven mode and steam turbine-driven mode. The data shows that steam turbine-driven induced fans mode can avoid the start-up problems caused by the large capacity fans and remarkably lower the power consumpition rate of station service. |
