Abstract
Dust is one of the flue gas pollutants in coal-fired power plants. In coal-fired power plants without wet ESP installed, the synergistic dust removal effect of wet desulfurization tower directly affects the final dust emission concentration. In order to explore the synergistic dedusting effect of wet desulfurization tower and improve the synergistic dedusting performance of wet desulfurization tower, tests were carried out on five 300 MW coal-fired units in actual operation. The reliability and advantages of low pressure impactor (ELPI) measurement method were verified by analyzing and comparing the test results of different measurement methods for particulate matter. Through testing the dust concentration at the entrance and exit of the desulfurization tower, obtained the influence rule of the structure of the wet desulfurization tower on its synergistic dedusting effect, revealed the irregular change of the efficiency of WFGD for PM10 and PM2.5, and expounded that the desulfurization tower measures adopted for ultra-low SO2 emission are helpful to improve the synergistic dust removal effect.
