Abstract

PURPOSE: The titled apparatus, having a conical dispersing plate with plural gas jetting holes and the column diameter of the apparatus just above the dispersing plate smaller than that of the upper part, and capable of preventing the formation of clinker.
CONSTITUTION: A gasifying apparatus 1 is equipped with a conical dispersing plate 20 with gas jetting holes opened a slant to the surface of the dispersing plate 20 for introducing a gas 23 thereinto while turning, and a jet steam pipe 22 in the center of the dispersing plte 20 for blowing a jet stream gas 24 into a fluidized bed 6. In order to make the gas flow velocity in the fluidized bed 6 just above the conical dispersing plate 20 higher than that in the upper fluidized bed 6, the column diameter of the apparatus 1 just above the dispersing plate 20 is reduced from that of the upper part. Preferably, the column diameter just above the dispersing plate 20 is reduced to make the gas flow velocity just above the dispersing plate 20 three times or more the fluidization starting velocity (V) of the particles in the bed 6 and the gas flow velocity in the upper part three times or less the velocity (V).
