文摘

失败的工作讨论问题的水壶持有融铅镀锌厂。CFD代码流利使用计算方法用于解决这个问题。几何是建立在策略解决环境和三维湍流,燃烧和辐射传热应用。研究显示检测的热点完全相同的位置观察到植物的水壶。这证实了CFD模型的有效性。基于该模型的建议,克服水壶膨胀。这两种方法建议。,微分热水壶和减少燃烧器的宽度。这两种选择的影响研究使用CFD模型和结果的有效性进行了讨论和比较使用表面无量纲参数表示的温度分布及烟气温度。基于结果的简易几何水壶加热。 The proposed novel design has the following features:  50% reduction in the fuel consumption and lower start-up time.  Separation of the zone of mechanical and thermal stresses and lower concentration of thermal stresses.  Increase in the heat transfer area and a reduction in the heat losses through the exhaust.  Reduction in the amount of lead used for the operation.The present work discusses problem of failure of kettle holding molten lead in a galvanizing plant. A CFD code Fluent was used to solve the problem using computational approach. The geometry is built in the GAMBIT environment and 3D solvers for turbulence, combustion and radiation heat transfer was applied. The study revealed the detection of the hot spot exactly at the same location of the kettle that was observed at the plant. This confirms the validity of the CFD Model. Based on this model the suggestions are made to overcome kettle bulging. For this two approaches are suggested. They are, differential heating of the kettle and the reduction in the width of the burner. The effect of both these alternatives is studied using a CFD model and the effectiveness of the results are discussed and compared using dimensionless surface parameter representing the temperature distribution and flue gas temperature. Based on the results obtained an improvised geometry for the kettle heating is proposed. The proposed novel design has the following features:  50% reduction in the fuel consumption and lower start-up time.  Separation of the zone of mechanical and thermal stresses and lower concentration of thermal stresses.  Increase in the heat transfer area and a reduction in the heat losses through the exhaust.  Reduction in the amount of lead used for the operation.
