Patent ID: 8110029

Claim:
An optimized pollutant removal system [ 1000 ] in a boiler system burning a fuel, functioning to reduce operating costs while maintaining pollutants of a flue gas stream below an acceptable limit comprising: a scrubber [ 1300 ] for dispersing a neutralizer into the flue gas stream removing SO x gasses; a sorbent injection subsystem [ 1500 ] having a sorbent chamber [ 1550 ] for receiving said flue gas stream, the sorbent injection system [ 1500 ] adapted to disperse sorbent particles within the flue gas stream at a defined rate, the sorbent particles adapted to adsorb gaseous pollutants; a filter [ 1600 ] coupled to the sorbent chamber [ 1550 ] for filtering the sorbent particles having adsorbed gaseous pollutants out of the flue gases; a stack [ 1700 ] coupled to the filter [ 1600 ] for releasing the filtered flue gases; a stack sensor [ 1710 ] for monitoring an amount of gaseous pollutant exiting the stack [ 1710 ]; a controller [ 1800 ] coupled to the scrubber [ 1300 ], the sorbent injection subsystem [ 1500 ] and the stack sensor [ 1710 ] for reading the rate that neutralizer is provided into the flue gasses, the rate of the sorbent is dispersed by the sorbent injection subsystem, an amount of gaseous pollutant in the stack [ 1700 ], a unit cost of the neutralizer and the sorbent, and for providing a signal adjusting the rate of neutralizer and sorbent dispersed to reduce said boiler operating costs while maintaining gaseous pollutant levels within predetermined acceptable levels.
