Within the framework of a two-temperature approximation, 
mathematical simulation of the process of filtrational evaporative 
cooling of a heat-releasing bed is performed. Based on this, an engineering 
method for calculating the cooling of a granular bed has been developed; 
it allows one to determine the position and size of the evaporation 
zone and pressure drops in the system. The conditions for the existence 
of various regimes of evaporative cooling (the presence of one, two, 
or three zones of heating and evaporation of a heat carrier) have 
been obtained in dimensionless form.
