Description
Cyclone separators are commonly used in various industries to remove particles from gas flows using centrifugal force. The square cyclone is an effective filtering tool for high-temperature gas in Circulating Fluidized Bed (CFB) boilers. The focus of this research is to offer an optimized design that enhances the separation efficiency of the square gas cyclone. The conical section of the typical square cyclone with a single cone is converted to a double inverse-cone for this particular purpose. The Eulerian-Lagrangian two-phase approach is used to perform a three-dimensional Computational Fluid Dynamics (CFD) simulation by solving the Reynolds-Averaged Navier-Stokes equations using the Reynolds Stress Model (RSM) turbulence model. The Discrete Random Walk (DRW) model is implemented to estimate the turbulent dispersion of particles. To maximize separation efficiency, the Taguchi method is adopted as a Design of Experiment (DoE) approach. The Analysis of Variance (ANOVA) is employed to identify the relative contribution of each parameter to the operation of the gas cyclone as the cone height provides the least effect on cyclone performance, however, cone diameter has the greatest impact. It is demonstrated that the optimal levels of factors for cone diameter, body height, and cone height are 0.5, 1.25, and 1.5, respectively. Compared to the baseline square cyclone, the optimized case led to the maximum improvement in efficiency by 16.2%.| Period | 19 Oct 2023 |
