This article introduces the 660MW supercritical air cooling unit installed with low temperature economizer in front of the dirt catcher. Through recovery of heat of flue gas, the energy-saving and cost-reducing effect and Atmospheric pollutants emission reduction effect are analyzed. And adjusting method is proposed for electrostatic precipitator facility. The results show that after installing the low temperature economizer, the turbine heat rate is reduced by 28.38kJ/kWh and the power supply coal consumption is reduced by 1.15 g/kWh. The desulfurization system water consumption is reduced obviously, the electric precipitation efficiency is improved, and the overall economic benefit is remarkable.
