Results of modeling of the process of heat transfer from 
a circular pipe filled with granular bed with allowance for the longitudinal 
thermal conductivity with boundary conditions of the first and second 
kind have been presented. The dependences for calculation of the thermal-stabilization 
portion and the active heat-exchange length that reflect the influence 
of the hydrodynamic regime of flow of the heat-transfer agent have 
been obtained.
