INVESTIGATION ON CLASSIFICATION EFFICIENCY FOR

2020-7-8 · Coal classifier has been in development due to its potential in improving the overall thermal efficiency of the power plant and the pollutant emissions reduction. It is scientifically essential and more reliable conducting an experimental investigation on such an important topic. Nevertheless, it is costly, and complex to access the real-time operating situation inside the coal classifier. On the other hand, conducting numerical modelling using CFD code with a three-dimensional designed geometry has been proven as a valid tool to explain the mechanism behind the complicated flows inside the coal classifier, which can be only acquired through expensive real-time experiments. Ataş et al. used a three-dimensional CFD modelling to numerically analyse the flow inside the geometry of a vertical spindle mill static classifier at different vane angles. Four designs were numerically analysed, and the best design was chosen and experimentally validated. The numerical results showed that a greater separation efficiency and an increment in the coal mass flow rate to the burner was achieved by using plates to control and direct the flow inside the classifier.
