3-D NUMERICAL SIMULATION OF TWO-PHASE FLOW DURING SEPARATION PROCESS OF COAL POWDER IN MILL INERTIAL SEPARATOR
Апстракт
This paper presents the results of CFD simulation of multiphase flow within inertial separator
in ventilation mill N. 400.42 of „TENT B2“ thermal power plant. Obtained results impersonate
the influence of lower flaps positions within the separator on fineness of coal powder grinding
on the exit of mill separator.
According to the real size model, 3D geometry with high rate of resemblance has been made.
Taking in consideration number of cells, convergence time period and accuracy of the obtained
solutions, appropriate numerical grid has been performed and used in simulations. Standard k-ε
model for solving the gas phase turbulent model is used. Modeling of monodisperse coal
particles flow within the gas phase is performed by use of integrated Lagrangian DPM
(Discrete Phase Model) method. The measurements obtained on real time scale model are used
in purpose of setting the boundary conditions in case of horizontal position of the lower
regulation flaps - S13. Afterwards, simul...ations with setting the flaps in 3 new/different
positions have been performed.
Results show the influence of the lower regulation flaps positions on the coal powder
distribution and residual of coal particles on particular sieves on the outflow surface of inertial
separator. The trends of inflection of these parameters can be c
