37. A method for reducing heavy metal emissions comprising:
-
burning a heavy metal containing fuel in a combustion chamber; introducing molecular halogen or one or more halogen precursors into an exhaust stream produced as a result of the burning of the heavy metal containing fuel having a temperature greater than about 1000°
F.; andintroducing a sorbent into the exhaust stream upstream of an air pre-heater (APH); wherein the halogen and sorbent material are introduced at a ratio of from about 0.7 to about 5.7 moles of halogen per pound (lb) of sorbent material. - View Dependent Claims (38, 39, 40, 41, 42, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54)
