摘要:
 作为一种新型燃烧装置,循环流化床克服了以燃煤为主的工业锅炉的很多弊端,使燃烧效率提高、污染物减少。针对实验研究流化床相关的传热特性,费用昂贵,且受环境条件的影响严重的问题,运用 FLUENT170软件作为数值模拟工具就可以解决。依据Tong Zhao等人的实验结果,运用了简化为循环流化床二维平面结构,模拟内部流动和燃烧过程,研究了床温与辐射传热对总传热系数的影响。并且经过理论计算,给出了三条热流密度值沿反应器高度方向的分布规律,为优化设计提供了参考。
Abstract:
 As a new type of combustion device, circulating fluidized bed has overcame many disadvantages of coal fired industrial boilers. It has improved combustion efficiency and reduced pollutants.The heat transfer characteristics related to fluidized bed are expensive and are subject to environmental conditions.The FLUENT17.0 software is used as a platform for numerical simulation to solve.Numerical simulations are based on experiments by Tong Zhao et al. A simplified two-dimensional structure of circulating fluidized bed is applied to simulate the internal flow process and combustion process, and the heat transfer problem of fluidized bed is further studied. Based on the heat transfer model, the influence of the bed temperature and radiation heat transfer on the total heat transfer coefficient is researched.After theoretical calculation, the three distribution laws of heat flux density along the height direction of reactor are found, which provides reference for optimization reference.
