| Summary: | The design and performance of a cyclone is determined by three non-physical parameters of assessment which are inlet velocity, pressure drop and collection efficiency. In order to achieve optimal operating cost is it important to have accurate prediction of cyclones pressure drop and collection efficiency. This was achieved by understanding the effects of varying inlet velocity from 15m/s, 17.5m/s,22.5m/s and 25m/s. Varying the inlet velocity in an increasing manner of the cyclone further increased the pressure drop and collection efficiency.
Hand calculation and simulation was done using a model of Stairmands High Efficiency cyclone. Data attained from the sample of ash collected at the boiler’s output was used for the hand calculation. ANSYS FLUENT software was used to simulate a cyclone with similar parameters. Both the results were compared to attain the optimal inlet velocity. The optimal performance was attained by having 20m/s as the inlet velocity.
Twelve cyclones were configures in series with an inlet ducting and outlet ducting. The simulation was made with having all cyclones to attain 20m/s as their inlet velocity. However , due to improper dispersion of gas flow the required inlet velocity was not achieved. Modification by partitioning using baffle plates of the inlet ducting caused a better flow of gas but in turn resulted in the formation of vortex in both the inlet and outlet ducting. The vortex formation was not achieved. Modification by partitioning using baffle plates of the inlet ducting cause a better flow of gas but in |
