Description

Particulate matter(PM) measurements were performed at the inlet and outlet of Fabric filter(FF) and the outlet of limestone-gypsum wet flue gas desulfurization (WFGD) tower at a 220MW pulverized coal fired power plant unit, and the PM formation characteristics, the performance characteristics of FF and the influence of WFGD to PM emission were discussed. The results showed that PM were of bimodal size distribution. The concentration of PMs larger than 2.5μm reduced in the WFGD while PMs less than 2.5μm particularly the PM diameter around 0.5μm increased due to the ultrafine PM aggregation as well as new PM formation from gypsum slurry entrainment.
