Abstract
The results of the analysis of calculated expressions obtained by different researchers to determine the hydraulic resistance of the dense layer consisting of different types (spherical particles, pellets, particles of arbitrary shape) were presented. The powered hydraulic resistance coeffi cient was used as a criterion to identify common patterns depending on the hydraulic resistance of the layer on the temperature and the rate of fi ltration. It is shown that depending on the nature of the hydraulic resistance of the layer porosity hardly affects the shape of the particles. The authors have recommended the formula by which you can reliably calculate the coefficient of hydraulic resistance of the pellet layer in their natural filling and the absence of a signifi cant amount of detail, and therefore determine the energy loss in the layer and in general throughout the gas path in roasting plants.
