| Abstract: | An overview of pollution and retention of trace in coal combustion is presented in this paper.The environmental pollution and the harm on human being health of trace arsenic in coal combustion are reviewed.Arsenic transformation and partitioning in coal combustion systems as well as the species of arsenic in flue gas are discussed.And the arsenic emission factors for coal fired utility boilers,for coal fired industrial boilers,and for coal fired commercial/instiutional boiles in USA are displayed.Finally the mechanism of arsenic sorption with different sorbents and the feasibility of decreasing arsenic emission by sorbents in coal combustion are put forward.Research on trace arsenic emission in coal combustion should be taken into account.; |
