Good knowledge of thermal balance is a prerequisite of successful mastering of the processes of heat and water transfer within a body. Given the reflective power of the substance surface under consideration, the analysis of the thermal balance of a loose disperse material was performed. A sample of milled peat served as the loose disperse material exposed to infrared heating. The practical results were compared to those available in the literature. One of the key results of the experiment represents identification of the radiation balance of the substance. Further research of the heat accumulation capacity rad will make it possible to identify the boundary conditions (energy and mass at the body boundary) required to formulate and solve the boundary problem of thermal and moisture transfer. The latter will make it possible to project and to manage the thermal and moisture mode of materials in terms of timing and depth subject to thermal processes underway on their surface
