PURPOSE:To perform effectively the temperature rise of fluidized bed at starting-up stage by combusting fuel with high efficiency. CONSTITUTION:The central part of the fluidized bed apparatus is provided with a dispersing plate with the heap-like portion 3 and also the burner 7 for starting-up below the dispersing plate. The heap-like portion is formed by folding a flat plate into a roof- like shape, a conical shape, or a polypyramid shape, with flat edge portions 2. With such a dispersing plate with the heap-like portion 3 and the flat portion 2, in which hot air from the burner 7 provided below the heap-like portion is made to pass by the heap- like portion 3 and a fluidizing gas is supplied from the flat portion 2, the start-up heating can be attained with very high efficiency. |
