Abstract: Featured by long-term stable dust emissions, high adaptability to varieties of coal, low investments, less land occupation and low maintenance costs, the electrostatic-fabric integrated precipitator (EFIP) technology has been widely used in coal-fired power plants in China in recent years. The removal efficiency of SO₃ by EFIP exceeds 60%, which can be boosted to more than 80% after spraying a small amount of alkaline adsorbent. The removal efficiency of Hg^P by EFIP exceeds 99%. As for gaseous and total amount of mercury, though affected by the distribution of mercury in flue gas, the removal efficiency of gaseous mercury can still be improved to over 90% after spraying the adsorbents. Compared with other pollutant removal equipment, EFIP has obvious advantages in its high efficiency and low cost for collaborative removal of gaseous pollutants such as SO₃ and Hg.
