Abstract

This paper discusses how to upgrade electrostatic precipitators (ESPs) with four 330 MW coal-fired generators. For the two four-field ESPs, the upgrading includes replacement of high-voltage electrodes and the high-voltage power sources. For the two five-field ESPs, only the power sources are retrofitted. The ESP outlet PM₁₀ and PM_2.5 emissions are less than 15 and 2 mg/m³, respectively. The flue gas desulfurization (FGD) can be effective for PM₁₀ emission reduction, but not for PM_2.5. This paper also presents the rapping and gas temperature effects on particle emission. When reducing the gas temperature from 150-160℃ to about 110℃, PM_2.5 emission from the ESP or FGD is always less than 2 mg/m³.

Key words
