CFD investigation on the flow and combustion in a 300 MWe tangentially fired pulverized-coal furnace

摘要: The characteristics of the flow, combustion and temperature in a 300 MWe tangentially fired pulverized-coal furnace are numerically studied using computational fluid dynamics. mathematical model is based on Eulerian description for continuum phase Lagrangian coal particles. reaction scheme was modeled eddy dissipation concept. application proper turbulence mandatory to generate accurate predictions flow heat transfer during combustion. current work presents comparative study identify suitable problem. Three models including standard k-e model, RNG k–e Reynolds Stress RSM examined. compared with published experimental data Zheng et al. (Proc Combust Inst 29: 811–818, 2002). proves be most offering satisfactory prediction velocity, species fields. detailed results presented this paper may enhance understanding complex patterns processes furnaces.
