摘 要：<正> Temperature distribution and control have been investigated in a liquefied petroleum gas （LPG） fluidized bed with hollowcorundum spheres （Al₂O₃） of 0.867-1.212 mm in diameter at moderately high temperatures （800-1100℃）. Experiments were carriedout for the air consumption coefficient α in the range of 0.3 to 1.0 and the fluidization number N in the range of 1.3 to 3.0. Particleproperties, initial bed height, α and N all affect temperature distribution in the bed. Bed temperature can be adjusted about 200℃ bycombined the adjusting of α and N.
