The formation distribution of mercury directly affects its sediment mode and efficiency of mercurey removal

the formation distribution of mercurey in flue gas is mainly related to atomic chlorine content in the coal and the temperature. Introduction of principle concerning chemical reation kinetics makes the homogenuous and heterogenuous oxidation reaction to obtain a certain development

however

it is believed that the heterogenuous reation is more approaching to reality. There are three methods which have potential of development for controlling mercury

namely the common physical coal cleaning technology

existing pollutant control facilities

and injecting sorbent

such as activated carbon etc.

into the flue gas. Finally

the development of mercurey removal techology must be depended on breakthrough in the theoritical aspect.
