| Abstract: | The problem of scale in the pipe line of circulating water in wet dust removal and desulfurization system in Beijing region was analyzed and the accumulation of Ca2+and SO 2- 4 was found to be the main cause for scale formation. Moreover, the appropriate desulfurizating method was proposed as the dominating factor to resolve the scaling problem and the addition of some effective coagulant proved to be very useful. |
