ABSTRACT:
The fuel is fed into a circulating fluidized bed steam generator using a feed system involving an air swept chute using secondary combustion air to suspend and carry the fuel into the fluidized bed combustor. The fuel is fed to the air swept chute through a gravity feed chute at a steep angle. The air swept chute is lined with an abrasion resistant material.
