Abstract:
In order to find out the optimal operation condition for return
sands cooler, a cooling model including heat and mass transfer
is constructed, and computer simulation is carried out. The
results are compared with the operation data obtained from a
fluidized bed sand cooler. A method is proposed for the
evaluation whether the practical cooling system provides a
reasonable energy cost performance. Several key points are
discussed concerning enhancement of particles concerning
enhancement of particles to air heat removal and improvement of
energy efficiency for cooling.
