Enhanced mercury capture from coal-fired power plants in the filtration baghouse using flue gas temperature as process control knob

摘要

A system (10) and associated method (100) for improved mercury removal from a flow containing combustion exhaust. The system (10) includes a filtration arrangement (12) through which the flow proceeds to remove material, including mercury, from the flow. The system (10) includes a sensor arrangement (84) sensing a mercury level within the flow downstream of the filtration arrangement (12) and providing a signal (88) indicative of the sensed mercury level. The system (10) includes an adjustable temperature control arrangement (90) changing a temperature of the combustion exhaust proceeding to the filtration arrangement (12) in response to the signal (88) indicative of the sensed mercury level.
