Abstract
A fluidized bed steam generation system and method in which recycled flue gases are used to assist in passing solid particulate material from the separator, through the loopseal, and back into the furnace. The solid particulate material separated in the cyclone separator and passed back to the furnace is assisted by recycled flue gases which have passed through the heat recovery section, an air heater, and a baghouse. The use of the recycled flue gases decreases the oxygen content which can cause oxidizing or burning of the solid particulate material which results in overheating or agglomeration of the loopseal.
