Abstract

The low-low temperature ESP (Electrostatic precipitator), reducing flue-gas operational temperature to improve dust removal performance, has been used gradually in engineering applications for the capture of fine particles in coal-fired power plant. The effects of temperature on discharge characteristics and dust charging characteristics are examined by using a lab-scale ESP setup. The offline dust resistivity was analyzed by DR dust electrical resistivity test instrument. Results indicate that the corona current decreases and the breakdown voltage increases with the decreasing temperature. The offline dust resistivity increases and then decreases when increasing the temperature with a peak around 130-150℃. In contrast to ESP operated at 130℃, the ESP operated at 90℃ shows a remarkable improvement of dust charging distribution as the decrease of dust resistance and velocity, especially for more residence time of particles in electric field.
