Abstract
An exemplary embodiment of the present invention provides an induced-draft injection system comprising an injection line in fluid communication with a duct under negative pressure, a particulate storage containing particulate, and a feeder receiving the particulate from the particulate storage and feeding the particulate to the injection line. The negative pressure in the duct supports the transportation of at least a portion of the particulate through the injection line and into the duct. Inside the duct, a binding portion of the particulate is bound to a portion of mercury in a flue gas passing through the duct, thus enabling a portion of the mercury to be filtered out of the flue gas.
