摘要:
根据传热学理论提出一种计算方法,用来研究大型竖式还原罐轴向传热和温度分布特性.结果表明:在内外绝热段,还原罐壁温沿高度方向呈线性递减规律;在自然对流换热段,还原罐壁温沿高度方向呈非线性递减,温度下降速率逐渐减小,但在壁厚减小处,温度下降速率出现突变。通过与数值模拟计算机现场实测温度对比,进一步验证了该计算方法的正确性。根据还原罐温度分布特性曲线,可得到罐体关键部位的温度,为解决还原罐材质的选择、还原罐的设计、罐体连接处密封材料的选择等时机工程问题提供参考依据。.
Abstract:
According to the theory of heart transfer, a calculating method was presented for investigate the heat transfer and temperature distribution along the avial direction of large vertical reduction pot. The results showed that the well temperature of reduction pot decreased linearly with increase in altitude of the adiabatic section. In the heat transfer area, the wall temperature decreased in a nonlinear way with increase in altitude, the decreasing rate of which gradually declined, but the decreasing rate changeed abruptly in the place of the declining thickness. And teh method was further verified through comparative analyses of CFD and the field measured temperature. According to the reduction pot temperature distribution curve, the temperature of keypart of the pot could be collected. This could provide reference for practical engineering to solve the problem of the reduction pot material selection, reduction pot design, sealing material of pot connection selection. These results could have certain engineering application value.
