PURPOSE: To provide an apparatus for supplying fluidized bed material to a circulating fluidized bed boiler which has a simple and rigid structure and can be manufactured at low cost. CONSTITUTION: An inventive apparatus comprises a mixing chamber having a first inlet for receiving solid fuel, a second inlet for receiving fluidized bed particles and an outlet coupled with a fuel supply point, a fuel supply means coupled with the first inlet of the mixing chamber and supplying solid fuel thereto, a first combustion air supply means 60 for supplying combustion air to a primary zone 42, and a second combustion air supply means 58 for supplying a portion of the combustion air directly to the mixing chamber in order to mix the combustion air with the fluidized bed particles in the mixing chamber and promoting supply of the mixture through the outlet thereof. The second combustion air supply means 58 and the first inlet of the mixing chamber are proximate to the first inlet and the combustion air is supplied into the mixing chamber in the tangential direction at a part separated from a fuel supply point 68. |
