It is known that particle accumulation is beneficial for dust removal in industry. In order to understand better particle accumulation mechanism, experiments were carried out to analyze the influence of flue gas temperature and humidity on ash accumulation. It is found that the Engineering Acid Dew Temperature (EADT) of flue gas is an important parameter that determines the efficiency of particle accumulation. When the gas temperature is lower than the EADT, the sulfuric acid in the flue gas and ash humidity rise dramatically, which leads to particle accumulation. In order to improve the collection efficiency, the flue gas temperature can be controlled to trigger particle accumulation.
