Abstract

Abstract: As a new combinatorial dust removal technique, the low-low temperature electrostatic precipitator(LLT-EP) has the defect of dust re-entrainment, so the mobile electrode electrostatic precipitator(MEEP) needs to be used together to ensure high dust removal efficiency. In this paper, the study on the technical characteristics, structure and mechanism of LLT-ESP+MEEP is carried out with some typical domestic and foreign cases being introduced and analyzed. Practices show that the LLT-ESP+MEEP technique is one of the technical combinations to achieve the ultra-low emission. Its outlet dust concentration can get lower than 15 mg/m³, meeting the ultra-low dust emission requirements of below 10 mg/m³ or even below 5 mg/m³ when the desulfurization system is integrated.

Key words: coal-fired power plant, ultra-low emission, LLT-ESP, dust re-entrainment, ESP innovation, MEEP
