Cyclones are widely used for removal dust of gaseous flows in industrial processes, and various studies were conducted in last decades to improve their performance parameters. However, in process industry, the reliable and uninterrupted operation of the cyclone is of the same importance as performance capabilities. In this work, the effect of vortex finder geometry on wearing processes is analyzed. The work relates to the gas-solid flow, which can be found in real dry-process kiln systems used in cement plants. Numerical studies were performed using Computational Fluid Dynamics software package, and covered three different geometrical versions of analyzed object. The relevant velocities of gas-solid medium within the cyclone, as well as pressure values were calculated with help of DES turbulence model. As a result - the design variant offering best balance between performance parameters and wearing resistance was pointed out.(original abstract)
