MODELING OF THE PROCESS OF MATERIAL MOVEMENT IN THE CROSS SECTION OF A ROTATING FURNACE WITH HEAT EXCHANGE DEVICES

The article is devoted to the study of the process of material movement in the cross-section of a rotating clinker kiln equipped with heat exchange devices in the form of an inclined parallelepiped, which is relevant. To optimize the geometric parameters of the heat exchange devices, digital modeling was carried out in specialized software systems, which reduced the design time, and also made it possible to study in detail the distribution of material in the furnace zones. Simulations were performed in the cross section of the furnace in the decarbonization zone for four and six heat exchangers with tilt angles from 30° to 50° in 5° increments. The simulation results showed that it is most advisable to use the angle of inclination α = 45 °, while in zone 1, 2 times and 1.6 times more material is distributed during unloading, than in the 2nd zone, in the case of six and four heat exchangers, respectively. In the zone under consideration, there is a mass of material about 5-10% less than the maximum, corresponding to an angle of inclination of 40° for both cases under consideration. It is advisable to use four heat exchange devices, since with an increase in the holes in the housing, its strength decreases, which requires additional research.
