ABSTRACT:
A method of operating a filtration system that filters flue gas, which includes particulate matter and a gaseous pollutant. The filtration system may include a fabric filter, which is cleaned with periodic pulse cleanings, a discharge electrode upstream of the fabric filter, which imparts an electric charge to at least some of the particulate matter before the particulate matter collects on the fabric filter, a sorbent, which is injected into the flue gas upstream of the fabric filter and absorbs at least some of the gaseous pollutant, and a fan, which draws the flue gas through the fabric filter. The filtration system may have a pulse cleaning interval setting that may be manipulated by an operator of the filtration system. The pulse cleaning interval setting may be the time between the pulse cleanings. The method may include the steps of: determining a cost of operating the filtration system at a first pulse cleaning interval setting; determining a cost of operating the filtration system at a second pulse cleaning interval setting; and comparing the cost of operating the filtration system at the first pulse cleaning interval setting with the cost of operating the filtration system at the second pulse cleaning interval.
