The article presents the results of the experimental determination of the
temperature conductivity coefficient of bulk fuel of plant origin. Solid bulk materials formed by
solid and gas phases are widely used in human economic activities. The quality indicators of
heterogeneous materials and products made from them are often determined by heat transfer
modes, which depend on thermophysical properties: thermal conductivity, heat capacity, thermal
diffusivity. These properties are functions of the properties of its solid and gas phases, pore volume
or space between solid particles and the specific volume of the solid phase, etc. This leads to a
significant effect on the thermophysical properties of mechanical, thermal and physicochemical
effects that materials are exposed to during operation. Therefore, the solution of the problems of
developing calculation methods and experimental determination of the properties of heterogeneous
materials, taking into account their structural characteristics, is of particular relevance. Thus, the
problem of controlling the thermophysical properties of heterogeneous materials which are formed
by solid and gas phases, and which are subject to mechanical, thermal, physicochemical effects
during operation, is of current interest. The paper presents a method for measuring thermophysical
properties based on the use of a regular regime of the first kind at various stages of the
measurement process.
