초록정보

A three-dimensional model for pulverized coal firing boiler has been developed to simulate the large-scale, steady-state and multi-phase systems. In the model, an Eulerian framework for the gas phase and a Lagrangian framework for the particles. The gas phase conservation equations of momentum, enthalpy and mixture fraction are solved employing κ-ε turbulent model. Coal devolatilization, gas phase oxidation, char oxidation, gas-particle interchange are modelled and radiative heat transfer is handled by a discrete transfer method. Model has been evaluated by comparison of predictions with operation data from Boryung power plant. The model predicts gas flows, temperatures, species concentrations, particle trajectories. The effects of burner firing angle on the flow and temperature field are also investigated. These comparisons show qualitative agreement of model predictions, and indicate that the model can be used to provide insights into boiler operation.
