Shorter Communications 843 CONCLUSIONS NOTATION 1. When compared under equivalent conditions of bed height Rem, particle Reynolds number at miniium fluidization and excess gas velocity (U -U,,,,), at 200 and 300°C bubbles were U,, minimum fluidization velocity, cm/s 75-85% of the sizes observed at room temperature.

u rnb minimum bubbling velocity, cm/s 2. Independent observations of the onset of slugging confirm U superficial gas velocity, cm/s this trend in that higher excess gas velocities were achieved before the bed started to slug. REFERENCES 3. The minimum bubbling velocity appears to be less sensitive [l] Singh B., Rigby G. R. and Callcott T. G., Trans. Instn. Gem. to temperature than U,,,, values reported in the literature.
