ABSTRACT:
A fluidized bed system and method utilizing two stage combustion in which solids in the flue gases from the combustion in the fluidized bed are separated and returned to the bed while the clean flue gases are mixed with gases containing oxygen to effect secondary combustion. The fluidized bed is operated at sub-stochiometric conditions and NOx scavengers are supplied to the flue gases.
