The residence-time distributions of particles in the lifting 
post of a circulating boiling bed were calculated on the basis of 
a model of longitudinal mixing of particles in this bed. It is shown 
that this model is well approximated by the standard -distribution. 
The dependence of the residence-time distribution function on the 
main parameters of the circulating boiling bed has been determined. 
The calculated and experimental distribution functions were compared.
