660MW超超临界机组汽轮机驱动引风机经济性分析

摘要

This paper takes Hua Neng luoyuan 2 í 660MW ultra supercritical units as an example. Electric motor and turbine driven forms are compared and analyzed for ID fan. The results show that although turbine driven ID fans increase the coal consumption rate, but it can save a lot of generating auxiliary power, increase the amount of power supply, and the economic benefit is remarkable, especially in low load.%本文以华能罗源2×660MW超超临界机组为例，对引风机采用电动机驱动和汽轮机驱动两种形式进行对比分析，结果表明，采用汽动引风机虽然增加了发电煤耗，但可以节省大量厂用电，增大了供电量，经济效益显著，尤其是在低负荷工况更加明显。
