| Abstract: | Based on Fluent, the flow of combustion of coal and decomposition of CaCO_3 in a big domestic high-performance precalciner are simulated by finite-rate/Eddy-dissipation and SIMPLE me-thod. The distributions of the velocity, temperature, pressure and volume fractions are given and analyzed. The results show that the flow trend of combustion of coal and decomposition of CaCO_3 in the precalciner are reasonable. Besides, the results also show that method of numerical simulation, together with methods of theory, experiment and local measure, is feasible to research the flow of combustion of coal and decomposition of CaCO_3in aprecalciner. |
