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.
