Abstract:
A mercury removal system for removing mercury from a flue gas, comprising:a combustion chamber having a combustion zone where a mixture of coal and air undergoes combustion; means for removing a partially combusted stream of said mixture of coal and air directly from said combustion zone; means for separating said partially combusted stream of said mixture of coal and air into a gas recycle stream and a thermally activated sorbent stream; a flue gas transport duct where said duct is coupled to an exit port of said combustion chamber and where said duct carries a flue gas stream away from said combustion chamber; means for contacting said thermally activated sorbent stream with a flow of the flue gas at a downstream location relative to said combustion chamber; and means for removal of said thermally activated sorbent stream containing said mercury.
