Abstract: A boosted no-lance injection system (BNLS) and methods of operating a combustion system to reduce acid gas or metal emissions in the flue gas is shown and described. In one embodiment, a BNLS includes an injection device, a high volumetric flow air mover, a transport air mover, a sorbent hopper and a mounting apparatus. In other embodiments, a method of operating a combustion system includes positioning the BNLS to inject into the ductwork, applying transport air and sorbent into the ductwork, and applying the high volumetric flow air into the ductwork. The result is methods and systems for reducing acid or metal emissions in the flue gas.
