Patent ID: 8375872

Claim:
A boiler furnace system and pollutant reduction apparatus comprising: a. a fuel source; b. a boiler furnace having at least one wall, wherein the boiler furnace comprises a combustion chamber, wherein the combustion chamber burns fuel from the fuel source, creating flue gas containing at least one pollutant; c. at least one measurement device located within the combustion chamber; d. at least one register located on the at least one wall of the combustion chamber, wherein the register comprises: i. at least one injector located the register for the injection of a slurry suspension into the combustion chamber, wherein the slurry suspension reacts with the at least one pollutant, forming flue gas with additional particulates, wherein the slurry containing a sorbent and a liquid; and ii. at least one opening to accommodate an injector, wherein the at least one opening is configured to carry momentum-providing gas such that the momentum-providing gas is capable of manipulates the flow rate of slurry suspension injected into the combustion chamber; e. a computer controlled slurry injection system capable of determining a slurry injection angle by a computer based on a real time temperature profile of the furnace, such that the slurry suspension is able to reach a computer determined injection location while remaining in a pre-determined temperature range; f. first duct work configured to carry the flue gas out of the combustion chamber; and g. at least one particulate control device located downstream from the boiler, wherein the first duct work delivers the flue gas with additional particulates to the at least one particulate control device, wherein the at least one particulate control device removes particulates from the flue gas with particulates, forming cleaned flue gas.
