| Abstract: | A mathematical model for atmospheric staged circulating fluidized bed combustion, which takes fluiddynamics, combustion, heat transfer, pollutants formation and retention, into account was developedin the Institute of Engineering Thermophysics (IET) recently. The model of gas solid flow at the bot-tom of the combustor was treated by the tworphase theory of fluidized bed and in the upper regionas a core-sannulus flow structure. The chemical species CO, CO2, H2, H2O, CH4, O2 and N2 wereconsidered in the reaction process. The mathematical model consisted of sub-models of fluid namics,coal heterogeneous and gas homogeneous chemical reactions, heat transfer, particle fragmentation andattrition, mass and energy balance etc. The developed code was applied to simulate an operating stagedcirculating fluidized bed combustion boiler of early design and the results were in good agreement withthe operating data. The main submodels and simulation results are given in this paper. |
