Sažetak

The paper defines the concept of porous charge and presents its general classification. The mechanisms of heat transfer that take place in this type of charge during heat treatment as an example of transport phenomenon were discussed. The main thermal property of porous charge is the effective thermal conductivity k_ef, which corresponds to the thermal conductivity of homogeneous substances. Introduction of the concept of the effective thermal conductivity substantially facilitates analysis of complex heat flow processes connected with heat treatment of porous charge.
