RESEARCH OF INFLUENCE OF FORMS AND POLYDISPERSITY OF PARTICLES ON THE CRITICAL SPEEDS DUST AND GAS FLOW
The brief results of the analysis of research of various modes of pneumotransport of fine bulk polydisperse materials are given in Russian, and foreign sources of scientific and technical information. Considered the following modes: cork, volatile transportation considerably different flow rates, transportation fine materials with particles of different sizes and geometrical shapes. Presents the results of the analysis of pneumatic transport technologies used in the energy industry of Russia and countries of the world community. Brief results of the analysis of the sources of Brief results of the analysis of the sources of scientific and technical information on the issue of determining the form and polydispersity fine particles polydisperse materials. It is revealed that studies conducted in different countries, contain the results at regard to the specific conditions of transportation of the materials. The conducted experiments were not taken into account the influence of the shape and polydispersed particles on the critical-ski speed of dust and gas streams. In technical and scientific sources of information not found formulas for determining the coefficients of the form and polydispersity fine particles polydisperse materials.
