Abstract
The present invention is directed to processes and apparatuses for reducing the content of pollutants in a boiler system flue gas resulting from combustion of fuel. The present invention discloses improved slurry injection techniques, re-circulation of flue gas to provide momentum to the injected slurry, a measurement system for obtaining system profile information and a system to optimize the reduction of pollutants in a flue gas by adjusting the injection of slurry suspension based on system profile information.
