A fluidized bed having two compartments and incorporating a pair of V-valve
and riser combination has been used to study the solid circulation across
the compartments as a function of various design and operating parameters.
Experimental studies show a variety of trends on the variation of solid cir
culation rate with parameters like aeration rates in the upstream bed, V-va
lve and riser, solid size and the upstream bed height. A solid circulation
model incorporating a pressure balance over the circulation loop has been d
eveloped to analyze the experimental findings. (C) 1999 Elsevier Science S.
