Abstract.

Intensification of production processes is one of the important problems of science and technology. Especially important is intensification of heat and mass transfer processes and, in particular, thermal processing of solid fuel. One of the most promising technologies of thermal processing of solid fuels with different ash content and degree of metamorphism is a fluidized bed whose economic and ecological indicators correspond to the best world standards. The article focuses on improving of the fluidized bed technology by providing pulsating air (gas) supply into the bed. The article presents a model of and a method of rational parameter calculation for the pulsating flow and solid particle motion and combustion in the fluidized bed. An effect of amplitude-frequency characteristics of the pulsating air supply on the completeness of solid fuel particles combustion in the fluidized bed was studied. Technical facilities (pulsators) were designed which can supply pulsing air flow into the fluidized bed and regulate mode shape and porosity of the air flow

Keywords: intensification, pulsing fluidized bed, pulsator.
