Abstract
In this paper, we analyzed the characteristics of fluidization of binary systems – wood waste-inert material. Experimental and theoretical study of the hydrodynamics of polydisperse materials. As a result of processing of experimental data, the regression equation is obtained for the speed of the beginning of fluidization with different contents of wood waste in a fluidized bed. Studies have shown that increasing the content of wood waste in the fluidized bed degrades the quality of the layer. This leads to significant increase of the velocity of fluidization start. At slow velocity, a gradual settling of large particles is possible. To avoid problems, it is necessary to increase the velocity of the liquefied agent. The content of wood fuel in the fluidized bed is determined to stabilize the operation of the combustion device. This content should be within 20... 30%
