Optimization of the Preheater Cyclone Separators Used in the Cement Industry

In this work, Taguchi methods have been utilized to optimize the pressure drop and particle collection efficiencies. These key parameters play an important role in process parameters of preheater cyclone separators used in the cement industry. The process parameters have been analyzed under varying vortex finder diameters (80, 120, and 160 mm), lengths of vortex finder (90, 130, and 170 mm), inlet velocities (9.51, 9.81, and 10.18 m/s), and inlet farin concentrations (0.24, 0.39, and 0.52 kg/m3). The settings of the test parameters were determined by using Taguchi's experimental design method. Orthogonal arrays of Taguchi, the signal-to-noise ratio, and the analysis of variance have been employed to find the optimal levels and to analyze the effects of the experiment parameters on pressure drop and collection efficiency accuracy values. Confirmation tests with the optimal levels of test parameters have been performed in order to check the effectiveness of the Taguchi optimization method. Results show that developed approach yields worthy results when comparing with observed values with confidence level of 99.5%, error rate in 3.85% for pressure drop, and 4.01% for collection efficiency.
