Abstract: Due to the low temperature flue gas in low-low temperature electrostatic precipitator (LLT-ESP) technology, certain measures should be taken to prevent the accumulation of dewing and knot ashes on the surface of high voltage ceramic insulator in order to ensure high operation stability. The paper designed three new insulator device structures of LLT-ESP, i.e., insulator within small chamber, insulator under wide beam and insulator within big incubator. Then the structural advantages and characteristics are analyzed respectively. At last, the applications of such technologies in Wenzhou and Huaiyin LLT-ESP devices are elaborated, where the insulator failure problem has been successfully solved.

Key words: LLT-ESP, insulating porcelain bushing, power plant, insulator chamber
