| 中文摘要: |
| 采用ANSYS软件对高温在线腐蚀监测机构进行温度场分析，分析了沿探针杆中心轴线和沿保温层径向的温度分布情况。分析采用比现场更苛刻的数据作为模拟数据。用传热学中精度较高的经验公式来计算管道内外侧的对流传热系数。模拟分析的结果对密封填料、探针、保温层、闸阀、法兰等的设计及选用具有指导作用。分析显示保温层壁温和理论计算结果误差在0.02%以内，所设计和选用的零部件能用于高温管道中。 |

| Using ANSYS software for the temperature field analysis of high temperature corrosion online monitoring mechanism, the paper analyzed the temperature distribution of the central axis of the probe pole and the radial of the thermal insulation layer. Taking the data more demanding than on site as analog data, calculated the convection heat transfer coefficient of the pipeline inside and outside with high accurate experience formula in heat transfer. The simulation results have a guiding role to the design and selection of sealing filler, probe, thermal insulation layer, gate valve, flange and so on. Analysis shows that the error of the temperature of thermal insulation layer wall compared with the theoretical calculation is less than 0.02%, the design and selection of components can be used to the high temperature pipe. |
