Low temperature corrosion is one of the key issues in application of low-low temperature electrostatic precipitator. The concentration of SO 3 affects the acid dew point temperature of flue gas. The exhaust temperature after the air preheater should be higher than the acid dew point temperature. The residual heat of flue gas is fully utilized by the low-temperature economizer. The efficiency of low-low temperature electrostatic precipitator is improved by the comprehensive effect of the condensation of SO 3 on the surface of the fine particles, the decrease of the specific resistance of the particles and the agglomeration of the fine particles.
